Protecting an Inherited Business in a Prenuptial Agreement
A family business you inherited can be at risk in divorce if its value grew during the marriage. Adv. Liron Elmaliach explains what the law says — and how a properly drafted prenuptial agreement protects the business and its future growth.
Why an Inherited Business Is at Risk in Marriage
Many people assume that a business they received as an inheritance is entirely their own — and will remain so regardless of what happens in the marriage. This assumption is legally incorrect and can lead to devastating consequences in divorce proceedings.
Israeli family law applies the balance of resources principle to assets accumulated during the marriage. While the inherited business itself may be treated as a personal asset (because it predates the marriage or was received as an inheritance), the courts have consistently held that the increase in value of that business during the marriage falls within the shared pool. If the business grew from ₪1,000,000 to ₪5,000,000 over ten years of marriage, your spouse may be entitled to half the ₪4,000,000 appreciation.
In addition, income generated by the business during the marriage — whether drawn as salary, dividends, or bonuses — is certainly treated as a joint marital resource under the law. This means that even profits that were re-invested back into the business can become a point of contention.
The case law on this point has evolved significantly. Courts examine the nature of the business growth: did the value increase due to passive market factors, or was it driven by the active involvement of one or both spouses? Active involvement — particularly by the non-owning spouse — can strengthen a claim for a larger share. Without a prenuptial agreement that addresses these questions, the outcome of any dispute is unpredictable.
How to Draft Protection for an Inherited Business
A prenuptial agreement that effectively protects an inherited business must address several interlocking components. A generic agreement that simply states "the business is mine" is unlikely to withstand scrutiny in court. Proper protection requires precision on each of the following elements:
Identifying the business asset. The agreement must precisely identify the business — its legal structure (sole proprietorship, partnership, or company), the shares or ownership percentage held by each party, the registered name and company number, and a valuation certificate or balance sheet as of the date the agreement is signed. This creates a clear baseline against which future growth can be measured.
What growth is shared — salary versus capital appreciation. The agreement can draw a clear line between the salary the owner draws from the business (treated as joint income) and the capital appreciation of the business itself (treated as the owner's personal asset). This distinction is legally recognised and, when properly documented, provides strong protection against a claim for half the business's growth.
Non-competition clause for the spouse. If the non-owning spouse works in or alongside the business, the agreement should define the scope of that work and confirm that it does not create an ownership interest. A clause can also address what happens if the relationship ends — preventing the former spouse from competing directly with the business, or soliciting its clients or employees.
Valuation at the time of signing. The agreement should attach a formal valuation of the business at the date of signing, prepared by a certified appraiser. This document becomes the baseline: it is what the owner "brought in," and only what exceeds it (if anything, subject to the agreement's terms) is open for discussion on divorce.
Buyout mechanism. In the event of divorce, the agreement can include a pre-agreed mechanism for valuing and buying out any share the non-owning spouse may be entitled to — at a predetermined formula or by an agreed appraiser — rather than leaving the matter to a contested expert battle in court. This protects the business from forced sale and gives both parties clarity on how any claim will be resolved.
