Customer: For Debra:Hello Debra,I would appreciate your take on this.I was in a 3.5 year dating relationship. I had my own house. He lived with his daughter, i.e. we were on separate official addresses. He paid for my rent in the city where he would often visit me and stay with me for a few days. He picked the places I rented with a committment of paying for them (I could not afford places he picked). Lease was in my name - he would transfer money to me for rent.Due to him not paying for the rent fully + me landing him a fair bit of money throughout our relationship, he ended up owing me a lot of money (there is a signed handwritten promissary note where he states how much money he owes me). He paid me back a good part of it, but still owed me several thousands dollars when we split in Spring of 2019.At that time we agreed that he would pay rent for space in my garage for the stuff he brought from his old house (he was going through divorce), because there was no room in his daughter's house/garage where he was living during his divorce, and during our relationship. I have texts confirming details of the garage rental agreement.Also, as of last spring, I started charging him interest on all the money he owed me. I have email informing him of the interest charges and his email where he says "ok".Now, the issue - He stoped paying for the Garage Rent and toward his debt early last Fall. His last payment was September of 2019. He came to my house in NOvember to help move my boat, at which time he collected several of his things from the garage, and I have not heard from him since.On May 1, 2020, I sent him a letter stating that he needs to pay me back (the original left over debt + unpaid rent for the garage + accumulated interest on both) or that I would sell his stuff or take legal action.On May 22, 2020, I received a threathening letter from his lawyer stating that I am not allowed sell anything, that I in fact owed him loads of money, and that I stole a boat from him. This is a boat that I purchased 100% with my money, when we were dating, under a promisse that he would buy it off of me within 6 months of the purchase. He never contributed a dime for the boat (other than pay for the damage he caused to the boat), so the boat was registered in my name and is fully mine. There is also a note, signed by him, stating that boat is fully mine and that he has no ownership in it.His lawyer encouraged me to take legal action, which I refused, stating that I wanted to resolve this out of the court.I never heard from his lawyer again. I kept sending montly debt statements (on the first of every month) with brief request for coopeartion and stating that I want to settle this.Now 6 months later (and 6 unanswered emails later), I want to wrap this up.I consulted with a lawyer who said the following:1. If this person and I did not have an official joint/shared address, did not have joint finances, and did not own anything together - there was no relationship and I should not talk about this as a relationship (the lawyer knows about the rent and him staying over).2. It is clear that this man has abandonded his things in my garage as it's been 14 months since the last time he paid rent, and it's been 6+ months of him (and his lawyer) ignoring my request for payment and resolution of the issue.3. That I have the right to sell or dispose of all the stuff in my garage and just keep the receipts and move on with my life.4. That if I wanted to be very polite - I could send them one last letter saying - you have 1 month to pay what you owe me and then I am starting to sell and /or dispose of the stuff in my garage.Does this sound right? I have received contradicting advice about having the right to sell the things in my garage, so I am now confused. His lawyer certainly thinks I am not allowed to sell anything.I just want to be done with this and I don't want to spend money on the legal procedures. I don't have money, and that is why i am so keen to get the money he owes me.Your input would be greatly appreciated Debra.Many thanks,
Maja
