This year I inherited a great deal of money from a relative (which my husband and I are planning on using to buy our first home). My husband has a daughter and I am just worried that if we file our taxes jointly this year...the bio mom could come back and try to get some of my inheritance.

My step-daughter is in my will...so its not a matter of excluding her from this money...I just don't want to be forced to give bio mom the money that she isn't entitled to.

Even though filing separately is usually not the best option....should I go this route?
