Post-nuptial agreements for couples who need clearer financial arrangements after marriage

A post-nuptial agreement is a legally binding document signed after marriage. It serves a similar purpose to a pre-nuptial agreement, but it is entered into during the marriage rather than before it.

Why couples use post-nuptial agreements

Couples may enter into a post-nuptial agreement for reasons such as:

• Mid-marriage financial planning after a major change in circumstances
• Protecting a business interest or other important asset
• Clarifying terms after reconciliation
• Coordinating financial arrangements with broader estate planning

Common issues covered

These agreements may address:

• Which assets or debts will be shared and which will remain excluded
• Spousal support rights and obligations
• Ownership and management of specific assets during the marriage

Requirements for enforceability

As with other domestic contracts in Ontario, full financial disclosure, independent legal advice, and proper execution are important.
