She game me money and I am afraid she will ask for it back it has been 9 mo

If your mother gives you money saying it is your inheritance can she ask for it back after 9 months

Give me some advice can she ask for it back after 9 months if she signed a paper

What does the paper say? "Inheritance" implies that she left something for you after she died; it sounds like she is still alive so doesn't quite sound like an "inheritance". Did she give you money and now is saying it's a loan? Tell us what she signed...
