Antenuptial agreement – in some jurisdictions the Family Law provides the option for such an antenuptial contract which pre-dates a marriage. Two people who plan marry, sign this agreement. Under the clauses of this agreement, the parties can set-up the procedure to regulate the ownership of their assets, acquired during the wedlock. As well how spouses will divide ownership of properties which they prospectively will achieve. For example, if they buy an apartment, who will hold the Title of it. This type of agreement seeks the purpose to regulate only material rights, not pecuniary rights (like parental rights).
It is similar to the postnuptial agreement. But spouses sign it during the marriage, not before it like the prenuptial contract.
