If someone inheirated houses before and during marriage is the other spouse entitled to any during equatable distribution. And if one house inheirated before marriage was sold during the marriage and it was owner financed is that monthly check after separation considered shared or just the spouses that inherited the property?

No, the other spouse is not entitled to a share in property that was inherited. Inheritances before marriage and during marriage are the separate property of the inheriting spouse, and they are not subject to equitable distribution.

If a house was inherited before marriage and sold during the marriage, the owner financed monthly payments after separation would be the separate property of the spouse that originally inherited the property.
