My father died last year, he had remarried several years earlier. Our step mother has told us that he never left a will, and was in thousands of pounds of debt. Myself and my sisters do not believe this, my father was a well paid man and travelled all over the world with work. We don't have any information regarding anything, and we really need help to find out what to do.

ANY question on law needs to include your general locale as laws vary by area. Since you referred to "pounds" I assume you are in the UK. You need to consult a solicitor. The estate will have to submitted to probate and the step mother required to account for all bills and assets.

The probate court can also check local solicitors to see if any made a will for him.
