Landlords duty of care to tenant?

do not get involved. You have ZERO obligations here (even if you want to do the right thing and try and help)

The only thing you can suggest is if custody is shared (via court agreement) then she needs to go back to court to update them about what is happening herself as there could be a breach of an agreed term.
Or she calls the Police herself if she she is being threatened in any way.
Advise her to speak to the CAB/Council for further advice.

I would agree with the above comment. You should not get involved in this. If you do then you will end up being the bad guy with both of them blaming you. Advise her to call the Police or speak to CAB about a restraining order.

Thank you that is my thoughts. But as we are bad landlords etc… Just seeking if any 118 readers have had this and did they do anything Thanks

She needs to seek legal advice,

You could offer some reasonable adjustment such as new locks or a door chain. Maybe suggest she buys a cctv camera to record the entrance to her home.

We are landlords, not parents or best friends.

Agree with the other comments. Sad as it is, you’re best not to get involved. You’re her landlord, not her social worker.
Her best support will be family, friends and (if neccessary) the police.

You clearly have an overly good connection with your tenant. As sad as this behaviour is, especially in front of a five year old, as previously stated, it’s not for you to get involved. Tensions in break ups are very difficult. Is there a relative or friend who could be at the property when the ex arrives? It sounds like your tenant might need emotional support but better it’s not you.

Yes, all of the above, the idea about putting a CCTV camera is a good idea, she could put that on the door top, when he becomes abusive she can say all of this is being recorded. It may work it may not but it’s the limit of your involvement.

CCTV sounds good, but don’t tell him or he may get violent. Tenant should take video to cab for advice.

Best to limit your involvement. As sad as the situation is. You don’t want to become the target of the aggressive behaviour.
As previously stated offer up some improvements/ advice but as soon as she tells her ex my Landlord said you, will put a target on your back.

As others have mentioned a cctv cam would be a reasonable idea. In effect you can kill 2 birds with one stone. As long as there is an active wireless Internet connection I can recommend the iegeek 360 cams. With one of these with a tenant you can give exclusive control to them so no accusations of privacy breaches etc and if/when the property is vacant a cheap smartphone with a data connection will allow you to keep an eye on the property (if not you’d need to recover the sd card). If the concern is escalation then the installation of the cam may dissuade more serious bad behaviour and ultimately help you protect the property. As long as the field of view is inside the property boundary then there are few issues. The only potential pitfall I can think of would be having to inform the tenant about GDPR if it gets pointed elsewhere but that would really be covering the bases. Boils down to what’s the concern? Are you feeling a moral obligation or are you thinking of a potential legal one.
