If you suspect that your spouse has hidden investments — mutual funds, fixed deposits, stocks, cryptocurrency, real estate held through third parties, or other financial holdings that have not been disclosed — you will be relieved to know that yes, hidden investments can significantly affect maintenance calculations in Mumbai, and courts have developed fairly robust mechanisms to uncover such concealment and ensure that maintenance is calculated based on a party's true, complete financial position rather than a deliberately incomplete disclosure.

When maintenance applications are filed under Section 24 of the Hindu Marriage Act, 1955, or under Section 144 of the Bharatiya Nagarik Suraksha Sanhita, 2023, which has replaced the earlier Section 125 of the Code of Criminal Procedure, both parties are required to file comprehensive affidavits of income, assets, and expenditure. These affidavits are meant to give the court a complete and honest picture of each spouse's financial standing, but it is unfortunately common for spouses seeking to minimise their maintenance exposure to disclose only their regular salary while omitting investment income, undisclosed bank accounts, mutual fund holdings, shares, cryptocurrency wallets, or property acquired in the names of family members specifically to keep it outside the scope of matrimonial proceedings.

The good news is that investments, by their very nature, tend to leave a documentary trail, which makes them considerably easier to trace than pure cash concealment, provided the right legal and investigative steps are taken. Under Order XI of the Code of Civil Procedure, 1908, which applies to Family Court proceedings, you can seek an order directing your spouse to produce specific categories of financial documents, including income tax returns for several preceding years, annual information statements or Form 26AS, demat account statements, mutual fund holding statements, bank statements reflecting investment-related debits and credits, and details of any fixed deposits or insurance policies with an investment component. A spouse who fails to comply with such a discovery order, or who provides incomplete disclosure, risks the court drawing an adverse inference against their credibility.

Beyond documents in your spouse's possession, courts can also summon records directly from third parties, including the Income Tax Department, which maintains records of high-value transactions, investments, and asset purchases through the Annual Information Statement framework, as well as from banks, mutual fund houses, depository participants managing demat accounts, and the Registrar of Companies where your spouse may hold undisclosed directorships or shareholdings. Income tax returns, in particular, often reveal investment income such as capital gains, dividends, or interest that would otherwise remain hidden if you relied solely on your spouse's voluntary disclosure.

A court-appointed forensic accountant or chartered accountant can play a particularly valuable role in cases involving suspected hidden investments, especially where your spouse is self-employed, runs a business, or has complex financial arrangements that make simple document review insufficient. Such a forensic investigation can trace fund flows across multiple accounts, identify patterns of investment activity inconsistent with the disclosed income, and produce an expert report that the court can rely upon when determining a realistic maintenance figure, particularly where there is credible reason to believe the disclosed financial picture is materially incomplete.

Lifestyle evidence also plays an important corroborating role when hidden investments are suspected. If your spouse's disclosed income appears modest, yet they continue to make new investments, purchase property, or maintain a lifestyle that would be difficult to sustain on the declared income alone, this discrepancy itself becomes relevant circumstantial evidence that courts have been willing to consider when assessing whether the true financial picture has been fully and honestly presented. Similarly, if you have personal knowledge of specific investments made during the marriage — perhaps you were previously aware of a particular mutual fund SIP, a stock trading account, or a property purchase — this knowledge, combined with a request for the court to direct disclosure of the current status of those specific investments, can be a highly effective starting point for uncovering concealment.

Property records deserve particular attention, since spouses attempting to shield assets from maintenance calculations sometimes transfer investments or purchase new property in the names of parents, siblings, or other close relatives. Certified copies of property registration records, which are public documents, can help establish a pattern of suspicious transfers, particularly where the timing coincides with the deterioration of the marriage or the initiation of matrimonial proceedings, and courts have shown a willingness to look behind such benami-style arrangements when genuinely assessing a party's true financial capacity for maintenance purposes.

Given how technical and document-intensive uncovering hidden investments can be, it is genuinely important to work with a lawyer experienced specifically in matrimonial financial disputes, who understands exactly which documents to request, which third parties to summon, and how to build a compelling case around investment trails, lifestyle evidence, and suspicious asset transfers. If you suspect your spouse has hidden investments that are affecting the fairness of your maintenance calculation in Mumbai, reaching out to the team at Aapka Legal Advice can help you develop a structured, methodical strategy for uncovering the complete financial picture.

It is also worth understanding that courts do not require you to produce an exact, dollar-for-dollar accounting of every hidden investment before adjusting a maintenance award; where a reasonable inference of concealment can be drawn from the totality of the evidence — incomplete disclosure, refusal to produce documents, unexplained lifestyle, or suspicious transfers — courts are entitled to, and frequently do, estimate a more realistic income and asset base and calculate maintenance accordingly, rather than being bound strictly by an incomplete or misleading affidavit.

If your spouse persists in non-disclosure despite discovery orders, this pattern of non-cooperation itself becomes an important factor working in your favour, since courts view deliberate concealment of investments seriously and often become considerably more receptive to the higher income and asset figures proposed by the other side once a clear pattern of non-transparency has been established on the record.

Given how demanding these financial investigations can be, many litigants in Mumbai find it valuable to consult retired judges who have handled similar maintenance disputes involving concealed investments. A retired judge with direct experience in matrimonial financial matters can offer realistic guidance on which forensic and discovery tools are likely to be most effective in your specific case, helping you and your lawyer prioritise your investigative efforts strategically.

With patient, methodical investigation and the right legal strategy, hidden investments can almost always be traced, ensuring that maintenance ultimately reflects your spouse's true and complete financial capacity.
