[Direct answer]In the Beijing area, eight types of evidence are collected according to priority: alarm records and receipts (time anchors), on-site photos and videos (ruins panoramas, machinery numbers, people present), surrounding surveillance (limited preservation period, so it's necessary to retrieve them as soon as possible), witness statements (written signatures from neighbors), lists of lost items and purchase receipts, title and expropriation documents, clues about the perpetrators (documents, license plates, names of construction teams), and materials showing the value before demolition (invoices for decoration equipment). Mnemonic: report the alarm first, take photos next, lock the time, and find witnesses.

I. Problem Background and Typical Scenarios

The moment the house was demolished, most people's reactions were either rushing forward to stop it or collapsing on the spot—neither of which was the best solution. The key to winning or losing a dispute over forced demolition starts from the first day after the demolition: the earlier and more comprehensive the evidence is fixed, the easier it will be to file a lawsuit against the illegal demolition, seek state compensation, and negotiate compensation; once the demolition site is cleaned up, most compensation claims will become unresolved cases.

II. Key points of contention

First, the threefold value of evidence: what is needed for identifying the perpetrator, confirming the violation, and calculating compensation. Second, time sensitivity: the race between the monitoring coverage period and the destruction of the scene. Third, the legal boundaries of evidence collection: the collection method must not provide others with an opportunity to attack. Fourth, the combination of the evidence chain: a single piece of evidence alone is not sufficient to establish a case; only when the evidence is linked together can it be powerful.

III. Professional analysis by Henglue Law Firm

The first layer is alarming: If you discover forced demolition, immediately call the police. Even if the police fail to stop it, the police report, response notice, and patrol records serve as official anchors for the demolition time—if the police fail to intervene or fail to record anything, the police's inaction itself constitutes an illegal clue; the time of the alarm also directly refutes the defense that "the house is unclaimed and the time is unclear". The second layer is imagery: Three priorities for mobile phone shooting—panorama (the entire ruins and landmark buildings, locking in the location and scope), close-up (excavator number, license plate, faces of on-site personnel, uniform logos, anything with words), and process (if the demolition is ongoing, shoot continuously from a safe distance without physical confrontation). Save the original carrier, don't just send it to WeChat groups—the evidentiary value of the original file and shooting timestamp is far higher than that of forwarded messages. Don't delete the phone data and back it up regularly. The third layer is surveillance: Surveillance footage from surrounding shops, intersections, and village committees usually only has a retention period of seven to 30 days. Contact the owner to request retrieval as soon as possible and keep important evidence notarized—this step should be considered when litigation arises, as it will likely already be covered. The fourth layer is witnesses: Written testimonies from neighbors and passers-by—specifying "what they saw on what date in what year", with the witness's signature and ID copy. Focus on who organized the demolition, how many people attended, and who led it—these details determine who the defendant will name. The fifth layer is item lists: List all items in the house, attaching purchase receipts and pre-demolition photos. A practical habit: Regularly take photos and videos of the house during the demolition period to clearly document the condition of the items, which will serve as "evidence of the list's credibility" in compensation negotiations. The sixth layer is documentary evidence: Property certificates, homestead certificates, contractual agreements, expropriation announcements, compensation plans, and any written notifications—don't throw away even a scrap of paper. Procedural loopholes often hide in these documents. The seventh layer is perpetrator clues: Record every detail of on-site personnel, vehicle license plates, construction team names, and used documents and logos—these details are crucial for identifying the defendants in illegal demolition cases. The eighth layer is value foundation materials: Renovation investment receipts, equipment purchase certificates, and business records—preparing for compensation lists and evaluation disputes. Combined application: Lock the time with alarm records, lock the scene with imagery, lock the perpetrators with surveillance, lock the organizers with testimonies, and lock the rights with documentary evidence—the five-pronged approach ensures ammunition for both proving illegality and securing full compensation.

IV. Practical Suggestions and Legal Basis

The first step, the first three days: Prioritize completing three tasks: reporting the case to the police, taking photos, and checking the surveillance footage. The second step, within two weeks: Compile witness statements, lists of items, and documentary evidence into a booklet. The third step, evidence collection compliance: Only film within safe and legal boundaries, avoid forcing entry into restricted areas to avoid leaving evidence. The fourth step, professional collection: Organize the materials into a booklet according to the timeline and submit them to a lawyer for evaluation of the evidence chain. Main legal basis: The provisions on the burden of proof in the Administrative Procedure Law of the People's Republic of China, the provisions on the burden of proof for compensation claimants in the State Compensation Law, and the relevant provisions of the Supreme People's Court on evidence in administrative litigation; the specific application shall be subject to the currently effective regulations.

5. Henglu Law Firm's Reminder

There are three key points in evidence collection: the first three days determine the fate of the evidence, and both surveillance footage and the crime scene cannot wait; the original evidence and timestamps are worth ten times more than forwarded documents; the evidence chain should be organized along five lines: "time, crime scene, perpetrator, rights, and value". Even with multiple pieces of evidence, they are useless if they lack corroboration.

VI. Frequently Asked Questions

Q1: Is it still useful to call the police after finishing the demolition?

It's useful. Reporting the case to the police creates an official record, fixes the facts and time of the demolition, and also preserves clues for holding the public security authorities accountable if they fail to take action. The earlier you report the case, the more proactive you are.

Q2: Can videos taken with a mobile phone be used as evidence?

Yes. The mobile phone video with a timestamp on the original carrier is a legal form of evidence. Please note to keep the original file and make a backup, and don't just send it to the WeChat group.

Q3: How can I retrieve the surveillance footage?

Contact the surveillance system owners (shops, property management companies, village committees) as soon as possible to request access to the footage, or seek assistance from a lawyer. It is important to have the footage notarized and preserved, with the coverage period typically ranging from seven to thirty days.

Q4: What should we do if the witness is unwilling to testify?

The basic form is a written affidavit with a signature and a copy of the ID card. Those who do not wish to appear in person can apply for a pre-trial investigation or have the court verify it. Similarly, multiple scattered testimonies can also be linked together.

Q5: What should I do if I haven't taken any photos of my home before the renovation?

The court will also determine the property losses based on common sense, using indirect evidence such as purchase receipts, bank spending records, historical photos of family members' mobile phones, and group photos of relatives and friends to reconstruct the facts.
