Contracts

We recently sold our home and need to be out in 30 days. At the time of signing the contract with the buyer we stated to our realtor that we would need to be flexible on the closing. She agreed, but states we have to be out even though we have not found another place to live. Can we back out on the sale without problems?

I have been asked by an individual interested in purchasing my house if I will sign a document which states I will agree to give him first oopportunity to purchase my house. I do not plan to sell until I retire in April 2008. I told this party I would agree to give him first opportunity(his parents are my neighbors) however I do not feel comfortable signing a document a year in advance when anything could happen as well as he may not be able to meet my offer on the house. I feel like I will come out on the short end of the stick -so to speak-- Legally-what should I do?

If I want to have a mixed martial arts place where people 18 and over have fights with a signed waiver would be able to have that with out having to go through the courts to get it an okay?

I have a Promissory Note is it the same as a Bill of Sale. I am current on my payment they terminated my contract. Do I have return my semi truck?

We are asking a subcontractor to sign a lien waiver of Feb. invoices. They refused because one invoice was not included. We rented equip from them during Feb but was billed in March. Do you go by billing date or date of equip usage to determine month due?
