Yes, the mortgaged property can still be sealed up, but it does not affect the mortgagee's exercise of rights. The people's court only recognizes the validity of the mortgage right set before the property is sealed up or detained. The people's court shall notify the mortgagee when it seals up or distrains the mortgaged property with the maximum amount set by the person subjected to execution. The amount of creditor's rights secured by the mortgagee shall not be increased after receiving the notice from the people's court. Although the people's court has not notified the mortgagee, but there is evidence to prove that the mortgagee knows the facts of seizure and seizure, the amount of creditor's rights secured by mortgage will not increase since he knows the facts.

Procedures required for house mortgage: To apply for bank house mortgage loan, all materials need to be prepared, including husband and wife ID card, household registration book, marriage certificate, real estate license, purchase contract or invoice, and bank statement of personal account for the last six months.

The mortgagee should pay attention to the following points when realizing the security interest through prosecution or arbitration:

1. Pay attention to the term of the security interest. Generally speaking, the limitation of action for creditor's rights is three years, but the real right for security belongs to the real right in nature and is not limited by the limitation of action. Therefore, the current judicial interpretation of the Security Law stipulates that the assured can exercise the security interest within three years after the limitation of action for the principal creditor's rights ends, and this "three years" should be the legal period of the security interest. The guarantee period agreed by the parties or required by the registration department is not legally binding on the existence of the security interest.

2. Creditors may bring a lawsuit on both the main contract dispute and the mortgage contract dispute, but they shall abide by the prescription of the main creditor's rights. At this time, the debtor and the mortgagor are the same defendant.

3. The mortgagee can bring a lawsuit on the realization of the mortgage alone during the existence of the security interest, at which time the mortgagor is the defendant.

4. When the mortgagee brings a lawsuit, he shall apply to the court for property preservation measures in time. The mortgagee has the right to collect the natural fruits separated from the mortgaged property and the legal fruits that the mortgagor can collect from the mortgaged property, and the fruits are used to pay the fees for collecting fruits, the interest of the principal creditor's rights and the principal creditor's rights. However, if the mortgagee fails to inform the debtor that the legal fruits of the mortgaged property should be paid off, the effectiveness of the mortgage is less than the fruits.

5. The mortgagee only has the right to discount, auction or sell the mortgaged property to get the price and get the priority compensation for the price. Unless otherwise agreed, the proceeds shall be repaid in order: the expenses for realizing the mortgage right, the interest of the principal creditor's rights and the principal creditor's rights.
