求救： attorney’s lien

我有个房客屡次不按时交租，一年半后就没再给她续租（7月搬出去了）， 搬出去前她一直求我续租（估计找过律师想告我不续租，没成，一年租期到后，就只给续了半年，并写了个notice 如果继续晚交，就不续租 她当时签字了。半年租期内继续晚交，所以半年后就不续了）。她然后又找律师说房子有个拉门roller 坏了，她3 月时拉门时伤了手腕。她说她做了therapy , ( 她一年半前搬进来之前因为在Amazon 伤了手腕，一直在做therapy 并从Amazon 那里拿到一笔补偿 每月????disability payment   。） 

昨天收到她律师来信，要我和我的保险公司联系付她的 attorney lien :

Please take notice this office has been retained to pursue a cause of action for damages arising from an injury sustained by xxx.  on your property located at by xxxxx. on or about March 15, 2024.

If you were insured at the time of this incident, please send the enclosed Attorney Lien to your insurance company. All future communications will then be directed to your insurance company.

请问，这事是我们应该直接给我的insurance company 联系？还是我应该直接回复她的律师？我们买了保险，那个roller 确实有点问题，拉门时需要抬起，但不至于伤人。怎么证明做therapy 是因为我的门伤了她？为啥我们(或我们的保险）该付她的attorney lien ？ 

请指教！不胜感激！
