Thank you for your question.
You, as the owner of the house, are liable for conditions on the property which act as a nuisance. A nuisance is where a condition on your property causes a neighbor to not be able to use or enjoy their property. This would be the likely claim that would be made against you by the neighbors regarding this matter.
Noise issuing from your property which disturbs the neighbors could be held to be a nuisance. Your liability will be based on how much you knew about the problem and whether you had any ability to fix it. As the owner of the property, you can demand that your daughter and her husband behave or face removal from the property. Because you have not taken this action, then you do in fact face exposure to the lawsuit.
The measure of damages, or your liability, will be determined by whether in fact the neighbor's ability to enjoy their property has been decreased. This could result in an injunction being issued against you, or an award for the reduction in value to the property because of the noise issues.
Further, you could be exposed to a nuisance abatement
order from the municipal government if the police find that your daughter and husband are violating noise ordinances or are breaching the police. You as the land owner are ultimately responsible for the continued violations.
