Is there a way I can get the house or a big part of the profit from selling it?

What one spouse wants is not exactly what the court may order. You have a legitimate claim on a major piece of property. Find a skilled family lawyer to advocate for you.

One point may be the repayment of the loan back to your parents before there is any distribution of proceeds to the parties. Also proof of further loans by parents may deplete the equity further to repay them back. You will need solid proof of those loans.

You are entitled to a "fair and equitable" distribution from the marital estate. Fair and equitable could include consideration of the source of the funds for the down payment on the home, if it can be proven. There is also commingling rule however, wherein an asset which was a party's separate, pre-marital property, has become marital through deeds transfers or other mixing of marital and separate assets. Division of property when there is a separate property claim is a nuanced area of the law, and a claimant should be represented by counsel. You inquiry suggests that you "are divorcing," which I assumed to mean that you have a divorce action pending. If you do not have an attorney, you should retain one. There is too much money at risk here.

The problem is that your parents gave you the money. If they had loaned it to the two of you, then you would both equally share the net equity. Talk with your attorney, but I think you will be stuck at 50/50.

A lot will depend upon the characterization of your parent's gifts. You should review all of the facts with a family law attorney.
