Yes, some couples choose to modify their Agreements, others choose to draft a Postnuptial Agreement. If you are choosing to modify a specific clause, the other terms will remain intact, unless both parties revoke the entire agreement in writing. Things change, children arrive, medical situations occur, inheritances happen, decisions change. Stating clear and specific intentions of your agreements solidifies the foundation you set by drafting a prenuptial agreement. Clarity in updating your prenuptial agreement terms shows a dedication to intention of drafting your prenup in the first place. Postnuptial agreements are drafted and signed after a couple has been married. If you want to disclose the current financial situations and change multiple sections of your prenuptial agreement, a postnup may be the agreement to create.
