How to claim FIRPTA withholding?

[Lior Reich]

hey guys,

my client sold a property in South bend (IN) in June 2017.

she never filed income tax before in the USA. her ex-husband owned the house until a year ago.

during the sale process - buyer is withholding 15% of the sale price of 52,000$

the house was originally bought in 2014 for 101,000$. during years as rental - only lost money due to neglected management.

what should my client do?

how can she claim her money back? she obviously only lost money with this property.

thank you
