Should I be fined for forgetting to pay the property fee?

Legal analysis: failure to pay property fees is a breach of contract, and there should be liquidated damages. The specific compensation standard of liquidated damages depends on how the contract is stipulated. If there is an agreement, it shall be handled according to the agreement, but it shall not exceed 30% of the losses caused; If there is no agreement or the agreement is not clear, it shall be liable for breach of contract to the extent that the breach actually causes losses to the other party.

Legal basis: Article 585 of the Civil Code of People's Republic of China (PRC), the parties may agree that one party shall pay a certain amount of liquidated damages to the other party according to the breach of contract, or agree on the calculation method of the amount of damages for breach of contract.
