Invalidation of separation agreement

If there is a signed Separation agreement and the two parties return to sharing a home and sharing a bank account does that invalidate the prior separation agreement if the two parties later separate again?

also would the original agreement be valid if assets were not all disclosed prior to signing?

Thank you.

The answer to both of these questions will depend on the language in your separation agreement. There may be a clause in your separation agreement that discusses reconciliation, and whether the agreement is still valid after a reconciliation.

Lack of disclosure can be grounds to contest an otherwise valid separation agreement, however, there may be language in your separation agreement directly addresses this issue. For instance, some agreements may contain a clause that states that both parties are satisfied with the disclosure given.
