Wife wants me to buy out of the house

Here’s my issue with this we’ve been in this house we bought for 4 yrs she’s asking for $14k of the $30k in equity. I have made every last mortgage payment and the only money she put in towards the purchase is $1500 and with a few things around the house it’s about $2500 So I feel she’s trying gain a large sum of money off of my dollar what I think is fair is $5k do I have just cause for this in court?

If the house was purchased during the marriage and purchased with marital funds (money earned during the marriage), then the house would be considered marital property and your wife would be entitled to one-half of the equity. Assets acquired during the marriage (but not inheritances) are subject to being divided equally among the spouses.
