JA: The Expert's answer will cost $10 to $100, depending on the issue type and time to respond. You'll see the exact amount on the next page and can decide then. It's way less expensive and more convenient than any face-to-face visit.
Customer: ok thank you My question as follows - I loaned my partner around $450,000 to pay his company debt - we have a written agreement between us stating that this is what he owes me ...it is now going on 3 years and he is about to sell his house ...and says that he may not be able to pay me as he has to pay out his mortgage and that maybe I should use the money I have given him as an investment into a house together - though I am unsure that I want to do this at this stage and he says it may be best if we then go and apply for separate mortgages to make up the money needed for the new home which is not yet built. We are not married and I am feeling uneasy about this arrangement. What are my rights? He is under a great deal of financial pressure and sure my money would ease it for him if he didn't have ot give it to me ...at the same time ...I am sure I have the right to ask for part thereof at least? and what is a resonable time frame ? HELP
JA: Have you talked to an Oklahoma lawyer about this?
Customer: oh right ...this is not an NZ site?
JA: What steps have you taken so far?
Customer: Well...I have not taken any ..as I say there is a written agreement in place between us and that is it
JA: Anything else you want the Lawyer to know before I connect you?
Customer: I want to know what is reasonable if I am to ask for the money or part thereof? as there was no time frame set for the repayment .....I am worried it may take a long time / be talked into putting my money into a house as a way of not getting it back? Need some advice
