You don't have to pay property fees if you owe money for more than 3 years.

The consequence of not paying the property fee for three years is that the property is sued and needs to bear corresponding legal responsibilities.

Failure to pay property fees is not uncommon in life, but it may lead to litigation risks. In essence, unpaid property fees are a kind of debt, that is to say, a typical creditor-debtor relationship has formed between property management units and owners. As long as the owner fails to fulfill the obligation to repay the debt on time, the creditor can take the form of prosecution to recover. In addition, non-payment or overdue payment of property fees also violates the property service contract between the two parties, and the owner needs to bear the liability for breach of contract. In the case of default by the owner, the property management unit, as the observant party, can also sue the owner at any time.

So, there is no exact time. Of course, in real life, property management units will not go to court as soon as they come, and most of them will negotiate privately with the owners who owe property fees first, but this does not affect their right to go to court.

To sum up, it can be summarized as the following two points:

First, unpaid property fees are essentially a breach of contract, which violates the relevant provisions of the property management contract.

Second, the non-breaching party (that is, the property management unit) can bring a lawsuit to the people's court at any time.
