He is by law as the Executor of the will required to show all the members of the family all expenses paid on the estate to cover the deceased person's debt. He is then as you know suppose to give out as outlined in the will what is due to each child.

I would not suggest selling the house unless it is the deceased persons. Then you have an option. Give the house to the siblings and be even. Have an appraisal done of the house and deduct what he has taken out once the house is sold from his share of the income.

Or sit down and be upfront and truthful with all those involved as they can and may take legal action against him.

It is in your best interest to get him to be humble and work this out.

He can pay his siblings if he would like to if your income would allow this. It does not sound as though it does.

Again, by law as Executor he is obligated by law to show an accounting. He needs to get the books in order and settle with his sisters in a way that is best for all.

All options are on the table as long as his sisters do not file a court action against him. Time is of the essence on this issue. He must take care of it asap.

If I may be of further help then please reply.

Then if the sisters are in good spirits about this and not about to file a court action then working with them is the best. This way down the line all could share in the sale of the house if the two of you are not living in it. It may be also if the house is his/yours that he may be able to get a loan. Settle with the sisters and if any undone settlements of the deceased are not taken care of at this time he can give the sisters the Power of Attorney or the Executrix position as a good faith effort on his part.

let me know if I may further assist.
