The Evolution of Income in Family Law: The Case of Short-Term Rentals

In today's landscape of separations and divorces, determining spousal support has become an increasingly complex challenge, going far beyond a simple review of tax returns. As an experienced family law attorney in Milan, Avv. Marco Bianucci witnesses daily how the digital economy and the so-called 'gig economy' have transformed the composition of family assets. A particularly relevant phenomenon in the city of Milan is that of short-term tourist rentals, managed through platforms like Airbnb, Booking, or Vrbo. These earnings, often variable and sometimes not fully traceable, represent a fundamental item in the family budget that, if concealed during separation proceedings, can significantly alter the fairness of the economic conditions established by the judge. Understanding how to identify, quantify, and prove the existence of these incomes is essential to ensure that spousal or child support reflects the real economic capacity of the parties.

The central issue concerns transparency. During marital cohabitation, income from short-term rentals often contributes to the family's standard of living, enabling vacations, private education, or simply a daily well-being greater than what salaries alone would allow. At the time of marital crisis, it is not uncommon for one party to attempt to minimize these earnings, claiming they are sporadic, negligible, or even non-existent gains, perhaps by deleting online listings or registering the account to third-party nominees. However, Italian family law imposes a duty of loyalty and full financial disclosure. Ignoring these income sources would mean accepting a distorted representation of reality, with serious prejudice to the weaker party and, above all, to the children.

The Regulatory Framework: Hidden Income and Spousal Support

Italian legislation, and in particular the case law of the Court of Cassation, establishes that spousal support (in separation) and divorce alimony must be calculated by considering the entire financial and income situation of the spouses. Therefore, it is not limited to the net income shown on the unified certificate or the 730 form, but an investigation into the actual economic availability must be conducted, which also includes exempt income, property income, and, indeed, proceeds from commercial or para-commercial activities such as short-term rentals. As a divorce lawyer in Milan, it is crucial to emphasize that the judge has the power, and the duty, to assess even income that escapes ordinary taxation or is artfully concealed, provided there are serious, precise, and consistent indications of its existence.

Short-term rentals present a legal and fiscal peculiarity that makes them a slippery slope in family proceedings. While tax regulations (with the flat tax) have simplified the emergence of this income, the very nature of the activity allows for a certain flexibility in cash flow management. The spouse managing the property might, for example, agree to cash payments upon guest arrival, or strategically suspend activity in the months preceding the court hearing to show a drop in income. However, the court assesses 'earning capacity' and 'income-generating capacity,' not just current income. Therefore, if a property has historically generated profits through short-term rentals, the sudden cessation of activity without justified reason can be considered by the judge as an attempt to withdraw resources, leading to a support determination based on presumed or potential income.

The Bianucci Law Firm's Approach: Investigation and Asset Reconstruction

The approach of Avv. Marco Bianucci, an experienced family law attorney in Milan, is distinguished by meticulous attention to the investigative and evidence-gathering phase. When there is suspicion that a spouse is hiding income from short-term rentals, making general complaints is not enough; a solid evidentiary framework must be built. The strategy of the Bianucci Law Firm begins with a thorough analysis of the opposing party's lifestyle and available real estate. Often, the combination of owning second homes (or even rooms in the main residence) and the absence of long-term registered rental agreements is the first warning sign suggesting the property is being used for undeclared or underestimated tourist rentals.

Investigative and Technological Tools

To transform suspicion into proof, the firm uses a combination of legal and technological tools. Firstly, it proceeds with requests for disclosure orders pursuant to art. 210 of the Italian Code of Civil Procedure directed at intermediary platforms (such as Airbnb or Booking) or banking institutions, to trace incoming cash flows. However, as international platforms can be complex to engage, Avv. Marco Bianucci often relies on the collaboration of technical consultants and authorized private investigators. These professionals can monitor property occupancy rates using specialized software that analyzes availability on online calendars, guest reviews, and price variations. A review dated during a period when the spouse claimed the property was vacant is strong documentary evidence that can dismantle the opposing defense.

Economic Valuation in Support Calculation

Once proof of short-term rental activity is obtained, the next step is economic quantification. It is not enough to state that the property is being rented out; one must demonstrate how much it earns. The Bianucci Law Firm develops realistic projections based on average market prices for the specific Milan area (from the historic center to expanding peripheral neighborhoods), seasonal occupancy rates, and accommodation types. This calculation is then presented to the judge to request an adjustment of the spousal support. The goal is not to punish the entrepreneurial spouse, but to restore procedural truth: if an apartment generates €20,000 in net profit per year, this must be accounted for in the comparison of incomes between the parties. This methodological rigor allows for the protection of the client from unfavorable agreements based on inaccurate income declarations.

The Pitfalls of Sham Ownership and Nominees

Another common tactic that Avv. Marco Bianucci encounters concerns the sham ownership of management activities. Often, the spouse who owns the property claims to have given it for free use to a parent, sibling, or new partner, who then formally manages the Airbnb account and collects the proceeds. In these cases, the legal challenge is to prove the simulation or the sham intermediation. It is necessary to demonstrate that the real economic beneficiary (the so-called 'dominus') remains the spouse. This requires meticulous work, analyzing who pays utilities, who manages the keys, who responds to guest messages, and where the money actually ends up (perhaps through cash withdrawals or return transfers). The experience gained as a divorce lawyer allows the firm to identify these inconsistencies and bring them to the attention of the Court with effective argumentation.

Furthermore, it is essential to consider the fiscal aspect. The concealment of these incomes not only has civil consequences in the calculation of support but also exposes individuals to audit risks from the Italian Revenue Agency. During negotiations for a consensual separation or a joint divorce, awareness of these risks can be an important negotiating leverage. Avv. Marco Bianucci uses this information with the utmost discretion and professionalism to facilitate the achievement of a fair agreement, avoiding litigation whenever possible, but remaining ready to defend the client's rights in court if the opposing party refuses any transparency. The correct reconstruction of assets is the only way to ensure that children maintain, as far as possible, the same standard of living enjoyed during marital cohabitation.

Frequently Asked Questions

How can I find out if my spouse is renting out our home on Airbnb without telling me?

Discovering an undeclared short-term rental activity requires a targeted investigation. The first step is to monitor online portals (Airbnb, Booking, Vrbo) by searching for the property using its location on the map and interior photos. Although the exact address is often hidden until booking, the photos are a strong identifying element. It is also useful to check reviews: if there are recent comments, it means the property is active. Legally, Avv. Marco Bianucci can request bank disclosure orders from the judge to search for incoming bank transfers from platforms or recurring payments for cleaning and industrial laundry services, which are typical indicators of this activity.

Are income from short-term rentals included in the calculation for spousal support?

Absolutely yes. For the purpose of determining spousal support and divorce alimony, all income and economic benefits available to the spouse are included, including those derived from short-term rentals, even if subject to flat tax or not yet declared to the tax authorities (undeclared income). The judge must assess the parties' actual economic capacity to ensure the maintenance of the standard of living or, at least, economic self-sufficiency. If these incomes are proven, they increase the income-generating capacity of the obligated spouse or decrease the need of the beneficiary spouse who receives them.

What happens if the Airbnb account is registered to a friend or relative of my ex?

This is a common form of evasion. If the account is registered to a third party but the proceeds actually end up at the spouse's disposal (or if the property is owned by the spouse and managed by a third party without a credible management contract), sham intermediation can be argued. It will be necessary to prove that the spouse is the true manager or beneficiary, for example, by demonstrating that they handle guest reception, maintenance, or receive money from the registered third party. This is a complex proof that requires an articulated defense strategy and often the support of private investigations.

Can I claim back payments if I discover these incomes after the divorce?

If evidence of intentionally hidden income emerges during the divorce proceedings, it is possible to request a revision of the divorce or separation conditions. Article 9 of the divorce law allows for the revision of judgments in the presence of supervening 'justified reasons' or pre-existing facts that were fraudulently concealed. If it is proven that the spouse lied about their economic conditions by hiding income from short-term rentals, one can ask the Court not only for a modification of the support for the future but, in some cases, also for compensation for damages or the return of sums that would have been due if the real income had been known from the beginning.
