Last year's property fee was paid, but next year's bill was lost. Can you indirectly prove last year?

I can't. Here are some ways to prove it:

1. Statement of property management company: You can apply for the statement of the previous year from the property management company to check whether the property management fee has been paid. When communicating with the property management company, you'd better provide specific housing information and relevant identification.

2. Bank running records: If you pay the property fee through electronic payment methods such as bank transfer and Alipay, you can check the corresponding bank running records or payment records to confirm the payment. This method needs to pay attention to protecting personal privacy and avoid revealing important account information.

3. Certificate of the owners' committee: If there is an owners' committee in your neighborhood or building, you can apply to the owners' committee for a written certificate to prove that you have paid the property fee for the previous year. The certificate should include specific information such as payment time, amount and payment method.
