What happens if the new business owner breaks the land contract?
We are subleasing our gas station business to new buyer. we are fiancing him short term (one month) part of the money till he gets all the reamining money from the bank( he is borrowing on his other houses – rental business). What happens if he does not come up the money? Can we legally ask him to forfeit his money ($90,000) if he does not com eup the money? what are the legal steps involved to get our money and also to get him out of the gas station if he does not bring the remaining money. We plan to have a land cotract short term like a brifge loan.

From a President is he personally respondsible for all debt from a corporation
I have a accountant that did corporation tax returns dating back about 15 years ago. And I was president of the corporation and the corporation went under and he still was billing on the corporation to me personally. The total is about 17,000.00 dollars now. He is my personal account and handling a Land Contract for me personally and the Payments that are made He took and Applied them to the bill of the corporation and now he is paid in full and Im broke with no money and my question is am I respondsible for all the past corporation bills personally. He says Im respondsible for all the debt of the corporation. Is this true?

The bills first came seperated and then the statements combined the two accounts and was put in my personal account. Then the account was changed back to the corporations name and my personal charges and Corporate where combined under the corporations name. Then later is was changed to my personal bill and he has taken all the money for the last year to pay off the account. I personally owe him about 2,000.00 dollars personally not 17,000.00 dollars.

Can you please reply to this question about this matter.

Thanks so much

power of attorney My husband is in jail.

power of attorney
My husband is in jail. Before he was arrested he had filed a small claims action against a employer who didnt pay him. The hearing came. Since he was in cusody I went in his place being I have a general power of attorney and it is noterized. The judge voiced the matter ”off calender”. Being I wasnt the plaintiff he mumbled some CCP and I wrote the CCP down . However that CCP the judge mumbled was not pertinant to a power of attoreney. What on earth can I do to get this matter heard without my husband present?
