Can I call the police if I don't formally sue the opposing lawyer for divorce?

You can call the police. If divorce is not formally prosecuted, the opposing lawyer can call the police by checking the hotel records, because the lawyer needs to apply to the court for an investigation order to check the room opening records. Only those involved in or suspected of committing crimes can be investigated, otherwise personal privacy will be violated. Legal basis: Article 1032 of the Civil Code stipulates that natural persons have the right to privacy. No organization or individual may infringe upon the privacy rights of others by spying, harassing, exposing or making public. Privacy is the private space, private activities and private information that natural people live in peace and don't want to be known by others.
