Mother didn't have a will

Because your mother died without a will, her property will pass through the process called, intestate succession.  Under this process the property will be divided equally between her children and any surviving spouse, with the surviving spouse guaranteed to receive a minimum of one-third of the estate. If no surviving spouse, then equally to her children. You will need to seek a letter of administration from the probate court in the county your mother lived in. Once filed you can officially demand the property be returned on behalf of the estate. If the property is not returned there may be criminal liability  Search the Lawyers.com attorney directory for a probate attorney that serves the county you live in.
