Lodger claiming that I am harassing?

Dear Kelly, you need to either get this person A out immediately or leave yourself. Everything you state above is on line with someone who has a personality disorder. I do not take stating this to you lightly! You have a child also, you need to inform the authorities that you feel uncomfortable and are worried for the behaviour of Person A and the safety of your child.

You write above -
Soon after signing the agreement in couple of occasions from very little reasons something A said and then claimed that A did not say it. A turned it around and made me look like I was lying. When I asked then A did not accept it and said that is not true and I have changed. A said that I have to be careful that I am doing illegal things and not to call police, but did not answer when I asked what are those things were. Then whenever I try to speak either A said I am saying illegal things or I am using my child as I said I want peace, because I have a child here. A’s whole attitude has changed like no speaking, banging doors, loudly switching lights.........

This behaviour is controlling and coercive, it is passive aggressive and manipulative. It is the behaviour of a personality disorder to to control with denials and lies, especially those with covert NPD. The outbursts are also a major red-flag. I am not a psychiatrist, but I have gone through much of this myself and have therefore had to learn a lot about it.

You need to be very careful about what you say, do not leave yourself open to them. The basic rule of thumb is to "grey-rock", which means, do not give them anything of yourself that they can use against you. You effectively need to become like a "grey rock", very boring and uninteresting. Do not communicate outside of basic necessity, do not ask them questions, do not answer their questions. This is absolutely necessary to avoid any further web within which you can be ensnared.

Also you need to be aware that they may be spreading lies about you to others so as to lock you into a compromised position. This "harassment" they are talking about is another big red flag. They could be telling lots of people, even the council, that you are harassing them. Do not confront them about it, just go to the authorities and state that you have concerns. Try and talk to their ex boss if you can, they will probably not talk to you, but you can tell them that they may be contacted in future by authorities.

Be very careful, about what you expose to them, and do not confront them. Get yourself rid of them as quietly and with as little drama as you can. Or leave yourself.

Again, you have said many things here that are too obvious to those who are familiar with the patterns to ignore. Go and educate yourself on Narcissistic Personality Disorder, both the overt and covert types. There are many Psychologists on Youtube who are very informative.

Do not tell them that you think this is what they are, do not say you are even researching it.

I am not saying you are in physical danger, but they can make your life absolute hell.

I am also not saying that they are for sure NPD or on the spectrum, but regardless, the symptoms of your experience you state are toxic, and regardless of whether they are or not, you need to get out. Do not give "second chances".

The switching from nice girl to bad girl is also a big red flag. They can behave normally for some time, and they will also pretend that things are ok so that you let your defences down. They will be gauging you to see what they can use or manage of you in the moment. Lieing is like breathing to them. Do not take . my word for it, go and educate yourself.

Do not let fear overtake you though, be as calm and rational and "grey rock" as you can be.

Sincerely and best wishes

If A is living with you and and it is your only home and you are sharing all the facilities in the property with her, then A is a lodger and not a tenant. A lodger is sometimes known as an "excluded occupier" which is possibly why the agreement given to you has been labelled "excluded tenancy" although the word tenancy is not strictly appropriate. But whatever the agreement says or does not say, it does not make a lodger into a tenant if the reality is that they are actually living with you as a lodger - in other words, sharing the facilities in your own home.
You can evict a lodger WITHOUT the need for a court order. You normally give 28 days notice but it depends what is stated on the agreement. If the person refuses to leave, you can in theory use reasonable force to remove them at the end of the notice, but you ought to get the police involved if that became necessary and you can tell them you have a young child to worry about. Some lawyers advice you should get a court order even if the person is a lodger, but it is not legally necessary. You should take careful notes of any conversations and avoid threatening language and use gentle persuasion to make her realise that in the end, all this has to come to an end eventually, so may as well make it end as amicably as possible.
If your agreement allows the person a long period in your property before their agreement expires and doesn't allow you to serve 28 days notice without reason, then you may have to try to bring the agreement to end by arguing that there has been a breach of contract by A. The obvious argument to make is that A, by her anti-social behaviour, has fundamentally caused a break down in the trust and confidence between the parties and you can argue that you are therefore entitled to evict her for good reason. Check the terms of the agreement. Even if the agreement gives no written right to terminate for anti-social behaviour, such a clause could be reasonably implied under normal contract principles.
Note: This is just opinion honestly given. It should not be relied upon as legal advice. You must take your own legal advice. No liability is accepted.

need to get rid asap

Surely this crazy woman “A” is a lodger, therefore you give her 28 days’ written notice to leave, and take all of her possessions with her. However. Your home is your home. It is your personal space, and you have a 5 year old child there, plus the neighbourhood is dodgy. You can make whatever rules you like in your own home, and she has to comply, so long as they aren’t breaking any laws or violating A’s human rights. Informing you when she is and isn’t in the house, and treating you with respect, are very basic and reasonable expectations, and if she continues to behave as she is, just get the police and ask them to come and remove her. When you explain that A is putting you and your child at risk in your own home, they will help you to remove her. This other “agreement” she has, explain to the police that it is NOT legally binding because it’s your own house, and you were duped into signing it. We all make mistakes. Best of luck.

As it is your home and you live there, she is almost certainly a lodger not a tenant. She is possibly a tenant if she can and does lock her door; you would need a solicitor to advise in this case.

Assuming lodger:
If the notice given has expired, then when she goes out, change the locks (obviously buy them in advance).
Get a trusted friend to be with you at this time for when she returns.

Do not allow her back in to your property.
Either put her belongings in weather-proof packaging outside for her to collect (but you need to be aware of the possibility of theft) or get your friend to pass them to her through a window.

Even if not a lodger, the above approach may be desirable for your safety. You are extremely unlikely to be acting illegally in what you have done so far; possibly unlawfully, but that would require your lodger to take legal action, not the police.

There is a small chance that if she can lock her room, then the actions I suggest would constitute illegal eviction, so getting advice from Citizens' Advice or a solicitor would be advisable.

35 years ago our family nearly helped X with their lodger Z. Unfortunately, Z had an unknown history which all became clear at Z's murder trial of X. Sadly Z had completely hid their previous murder conviction. I would implore you to take a safety first route.

Dear Kelly,
Legally your lodger, by sharing living space and facilities in your home where you live, is an "excluded occupier" and has no tenancy rights. You have asked her to leave and, having failed to do so, she is now trespassing. Courts take ages, and their findings may muddy the water. You and your child are at risk now.
1. Read the government advice at: https://www.gov.uk/rent-room-in-your-home/your-lodgers-tenancy-type. This will give you confidence to act - peacefully but firmly. Do not confront your lodger further.
2. Call the police, and explain the situation including the risk to your safety. Show them the government advice under 1. They will ask the lodger to move out immediately. The advantage to using the police is that your lodger is less likely to resist or try in future to take revenge against you or your property.

Don't delay - have this person out of your house by this evening. She has a job, so she can find somewhere else to stay.

Notwithstanding some relevant advice above, my Possession company PossessionFriend.uk would want to have a detailed conversation AND see whatever agreement you have signed.
Unfortunately, many landlords we help with eviction - Possession issues ( amongst others ) have entered into renting without a sufficient understanding of the very many regulations, laws and requirements. ( such understanding that might well have prevented them getting into the problem, or at least have much alleviated it )
I would not recommend dealing with this matter on the strength of a few online comments. Wishing you the best outcome to this and a Happy New Year.

Is A still there Kelly, or did you manage to get rid of her by now? I can’t imagine a Christmas with her in your house.

In the late autumn of 2018 I noted that with three lodgers in my own home, I should need an Additional Licence as the London Borough Council had decided it should apply to my locality. After reading the requirements, I decided that I didn't want door closers throughout my own home. I had the linked smoke alarms but there were further regulations and stipulations that would have meant more work and time on my part. Thus, I decided to give one lodger notice and to reduce to two thereby not needing the Licence. This lead to a complete change in mood on his part, to some threats and to him shutting himself in his room - even though I had offered to be as supportive as possible. One month's rent was withheld (an "admin" problem on his part) though the following month's rent was paid. Luckily, he left within the month's notice but had, in the mean time, consumed about £250 worth of my whisky and wine! I also had a visit from the Council's Enforcement Officer after he left; the officer was impressed with the house (and its four bedrooms and 4 bathrooms!). As stated in the advice to Kelly, there are always those with a personality disorder who may become a lodger. I always have an agreement and an inventory. My remaining lodgers are charming and helpful; I do hope Kelly's situation quickly resolved itself in a good way.
