The Single Allowance is not split automatically just because parents separate. It can be paid entirely to the person who submits the application or divided equally between those who exercise parental responsibility. This gives rise to understandable doubts: who receives the payment if the child lives mostly with one parent? Does the monthly maintenance change? What happens if custody is sole or if the other parent does not cooperate?
I want to help you distinguish the administrative payment of the Single Allowance from maintenance obligations toward children. We will see when a 50% allocation is provided for, which facts make the answer different, and why a written agreement or an existing court order should not be read superficially.
The rule: payment to the applicant or equal division
The application can be submitted by only one parent. Article 6 of Legislative Decree No. 230 of 2021 establishes that the application is filed by a parent, or by whoever exercises parental responsibility. The Single Allowance is therefore paid to the applicant, unless it is subsequently requested that it be disbursed in equal measure between those who exercise parental responsibility. Payment at 50% is thus an expressly provided modality, not an automatic consequence of separation.
The applicant does not necessarily coincide with the custodial parent. The parent with whom the child lives predominantly can submit the application and receive the entire sum, but this does not derive solely from the minor's residence. What matters first of all is the requested payment modality and, when there are conflicts, the content of the conditions of separation, divorce, or regulation of parental responsibility also counts.
Equal allocation concerns payment. If both parents exercise parental responsibility, the division provided for by law is in equal parts. It is not an allocation calculated based on income, the days the child spends with each parent, or individual expenses incurred. These elements can be decisive for maintenance, but they do not alone transform the credit of the Single Allowance into a percentage other than 50%. The regulatory reference is Article 6 of Legislative Decree No. 230 of 2021 in the text reported by the Official Gazette.
Joint custody, placement, and sole custody
Joint custody does not mean identical times. A child can live primarily with one parent and spend significant time with the other, while both maintain parental responsibility. In this situation, the law allows disbursement to the applicant or, upon request, equal division. The place where the minor habitually lives is therefore not enough on its own to resolve the issue of payment.
Maintenance follows different criteria. In decisions concerning children, the judge establishes times of stay, care arrangements, and the amount of each parent's financial contribution. To determine any maintenance allowance, they consider, among other elements, the child's current needs, the parents' financial resources, times of stay, and the value of care work. These criteria result from Article 337-ter of the civil code published on Normattiva.
Sole custody introduces a specific rule. When the child is placed in sole custody of a parent, Article 6 of Legislative Decree No. 230 of 2021 provides that, in the absence of an agreement, the Single Allowance belongs to the custodial parent. Sole custody should not be confused with simple predominant placement: in the first case, there is a different custody regime; in the second, as a rule, parental responsibility continues to be exercised by both.
A court order must be read in full. The formula "joint custody" does not exhaust the content of family conditions. It is necessary to understand whether the order or agreement expressly regulates the Single Allowance, whether it establishes a monthly contribution already calculated considering this income, and whether subsequent changes have intervened. Skipping these steps can lead to adding or subtracting amounts without a clear basis.
Single Allowance and child maintenance: two distinct levels
Payment does not automatically replace maintenance. The Single Allowance is a financial benefit linked to dependent children and the economic condition of the household relevant for ISEE purposes. Maintenance, on the other hand, is the contribution that each parent must ensure for the child's care, education, upbringing, and daily needs. Receiving the entire Single Allowance does not mean, by itself, that the other parent is freed from their contribution; likewise, receiving half does not determine by itself a reduction in the maintenance allowance.
What has already been regulated matters. If the separation conditions or the judge's order indicate how to consider the Single Allowance in calculating maintenance, that provision is the starting point. A precise phrase can establish that the benefit be attributed to one parent, that it be allocated, or that it has already been considered in quantifying the monthly contribution. If express rules are missing, it is not prudent to derive automatic compensation solely from bank movements.
An agreement can prevent concrete conflicts. Parents can choose to keep the full payment to one of them, for example because they directly bear many of the child's ordinary expenses, or request equal allocation. A useful agreement is not limited to saying "the Single Allowance remains with one of the parents": it clarifies whether this choice affects the amount of maintenance or not, from what moment it operates, and how any variations in custody or the child's cohabitation are handled.
The child's needs remain the reference point. It is not correct to treat the Single Allowance as a sum unrelated to the minor's daily life or as a prize intended for one of the two adults. The decision on who receives it must be consistent with the concrete organization of care and the overall contribution that each parent ensures. If there is a conflict that affects maintenance or custody, the solution does not consist in informally modifying a payment that has already been regulated.
ISEE, overall amount, and application updates
The division does not create two Single Allowances. The overall amount remains one for each child or household entitled to it; the request for 50% payment only distributes its credit between parents. Article 1 of Legislative Decree No. 230 of 2021 links the benefit to the economic condition of the household, measured through the ISEE. From March 2026, the calculation uses the new ISEE for family benefits and inclusion; for minor children, the rules on household composition remain relevant.
Separation can affect ISEE, but not uniformly. The composition of the household for ISEE purposes follows its own rules and does not always coincide with what seems most intuitive after the end of cohabitation. The presence of an order providing for periodic maintenance allowances, the other parent's family situation, and the child's cohabitation are data that can take on significance. For this reason, it is important that DSUs, family orders, and data communicated for the Single Allowance do not contradict each other.
For residents in Italy, an approved application does not have to be resubmitted each year. INPS circular no. 7 of 30 January 2026 confirms automatic renewal, unless the application has lapsed, been revoked, withdrawn or rejected. The ISEE must still be updated: without a valid assessment, the minimum amount is paid from March. Filing the DSU by 30 June allows arrears from March to be paid. For a new application, 30 June remains the deadline for entitlement from March; later applications take effect from the following month.
The case of adult children
The adult child can intervene directly. When the requirements set for the Single Allowance in favor of adult children are met, the child can submit the application in place of the parents and request direct payment of their share. This possibility is distinct from the allocation between parents and requires not overlapping the administrative relationship with the one relating to maintenance, which can remain governed by agreements or family provisions.
How to handle a disagreement over allocation
The first alternative is a clear understanding. If both parents agree on the allocation, they can choose full payment to one of them or payment in equal parts, using the envisaged administrative procedure. When a separation agreement or an order regarding children already exists, the choice should be compatible with what was established regarding maintenance. A modification communicated only orally leaves unresolved the problem of how the amounts received should be considered.
Dissent is not overcome with a unilateral withholding. If a parent believes the other is receiving sums that should be shared or considered in maintenance, they must first distinguish the payment level from that of family conditions. It may be necessary to clarify the meaning of the agreement already signed, reach a new understanding, or request the revision of the provisions governing the contribution for the children. Parents can request at any time the revision of provisions on custody, parental responsibility, and the amount or modality of the contribution.
The variation must have a concrete reason. A new sole custody arrangement, a stable change in the child's cohabitation, a different distribution of care times, or a significant change in economic conditions may require reconsidering the overall rules. The mere fact that the Single Allowance was paid into a different account does not prove, however, what maintenance is due nor does it authorize modifying the fixed obligations by oneself.
Few documents are needed, but the right ones. To put order into the matter, the separation, divorce, or custody order, any subsequent agreements, the relevant ISEE certification, and the data showing how the payment was arranged are normally central. There is no need to accumulate non-pertinent documents: the objective is to verify whether payment of the Single Allowance and maintenance contribution follow an already written rule or if it needs to be defined.
Errors that make finding a balance more difficult
Do not confuse 50% with a maintenance share. The equal payment provided for the Single Allowance does not establish that parents must bear all the child's expenses exactly in half. Maintenance follows the principle of proportionality and considers resources, care times, and the minor's needs. The allocation of payment can therefore be equal even when the monthly contribution between parents is not.
Do not use ISEE as a discretionary choice. ISEE is not data to be adapted to the convenience of one of the parents: it depends on the rules on the family household and the declarations made. Incorrect data can affect the overall amount of the benefit and make it harder to understand if payment was arranged correctly. Separation does not render the other parent's situation irrelevant for the purposes of the ISEE rules applicable to minor children.
Do not modify maintenance by compensation. If a parent receives more Single Allowance than expected, the other cannot assume they can reduce the established monthly contribution for this reason. First, it is necessary to understand whether the order already contemplated the benefit and whether the prerequisites for an agreed or judicial modification exist. Acting without this verification can create arrears and further conflict, instead of resolving the existing one.
Frequently asked questions
Can I ask for the Single Allowance to be split 50% after separation?
Yes, the request can also be submitted subsequently. Article 6 of Legislative Decree No. 230 of 2021 allows disbursement in equal measure between those who exercise parental responsibility. Before modifying payment, however, it is important to check whether an agreement or maintenance order already attributes a precise meaning to the benefit.
If my child lives predominantly with me, must I receive all of the Single Allowance?
No, predominant cohabitation does not require full payment on its own. With parental responsibility exercised by both, the sum can be disbursed to the applicant or divided in equal parts. Predominant cohabitation can instead take on significance in determining maintenance and evaluating daily expenses incurred for the child.
Can the other parent reduce maintenance because I receive the Single Allowance?
No, they cannot reduce it automatically. It is first necessary to verify what family conditions provide and whether the Single Allowance was considered in quantifying the contribution. If circumstances have truly changed, parents can agree on a new regulation or ask to modify provisions relating to the child's contribution.
What changes if custody is sole?
In the absence of an agreement, the Single Allowance belongs to the custodial parent. This rule applies to sole custody and not to the mere fact that the child spends more time with one of the parents. It is therefore necessary to read the order carefully: custody, placement, and modalities of exercising parental responsibility are not equivalent expressions.
Does the allocation of the Single Allowance modify ISEE?
The payment modality does not create two distinct ISEE values. The amount of the Single Allowance depends on the rules on the relevant family household and valid ISEE, not just the account to which the sum is credited. After separation, personal data, maintenance orders, and household composition must be consistent in the declarations used.
Putting order before changing payments
A clear solution protects the child above all. Before asking for a different allocation or connecting it to maintenance, it is advisable to identify the rule already contained in family conditions and distinguish what concerns payment from what concerns the overall contribution.
