Request details: Cooling off by electronic content certification


I asked for a cooling-off for the home repair contract construction contract that my mother had contracted.

My mother lives alone in a house a little far from where I live.
I try to see my face every weekend, but in the middle of the week, a housing renovation company suddenly visited me and signed a contract for repairing cracks in the outer wall and waterproofing the veranda.
It seems that the cracks in the outer wall were certainly a concern, but regarding the waterproofing work on the veranda, they were forced to sign a contract without an inspection and without knowing the grounds. I wanted to do it, so I called the remodeling company to confirm, but they said that the schedule for the repair work had not been decided yet, so I could cancel over the phone.
After that, when I looked at the contract again, there was an item "I fully understand the cooling-off period."

At first, I was going to cancel by phone, but I became uneasy, and through an acquaintance, I consulted with the Going Administrative Scrivener Office.
・ Cooling-off must be notified in writing
・Even if you send it in writing, send a content-certified mail with proof of delivery that can prove that it has arrived without error.
・ Feeling distrustful of the fact that the other party said that you can cancel even by phone
After explaining such things, I was also told that although there are rules such as methods and methods, I can also create and send sentences myself.
However, since there were only 4 days remaining in the cooling-off period, I gave top priority to sending it without any mistakes, so I asked for the writing and shipping.

After requesting a request, we will send you an email with a copy of the contract and information about the other party. On the other hand, I could understand what was needed and what was being done, so I was able to proceed with the procedure without worry, and the cooling-off was completed successfully.

Thank you very much.
