How to write the loss list written by the property company to the development company?

You should write it in the form of a work contact form, and you can download a copy on the Internet. This situation belongs to the maintenance period, and the property can directly contact the construction unit for maintenance. When you don't do it, send it in a written work contact letter. If you still don't perform your duties, it is recommended that the owner complain or solve it through legal channels, but you must provide the collected evidence, otherwise it will be difficult to go to court.
