Legal Question in Family Law in Maryland

Your wife's position is that since you haven't contributed to the equity since you left, you should not be entitled to share in any increase in that equity since then. However, it's highly unlikely that the equity is growing that fast. You need to consult with an experienced family attorney in the negotiation of this agreement. You should determine the fair market value of the property as of the date of your separation, either by agreement or by having an appraisal done or a market analysis by a realtor familiar with the neighborhood. Then subtract the balance of your mortgage(s), as of that date to compute the equity. If she is going to buy you out, she should refinance and pay you half that amount. If she can't do that, then agree on a deadline for selling the property. An attorney who's negotiated these agreements before will know how to insert language in the agreement that protects your interests.
