Why would anyone request a Guardian Ad Litem? The only reason they are assigned is for infancy, incapacity or disability.
If you're too young to not have one, then you cannot simply drop them without a compelling reason.
If you've been incapacitated, then you'd have to show the incapacity has been removed to get rid of one.
If you have a disability, then you would need to prove that the disability has been removed to get rid of one.
In any case, you can't simply dismiss them when it suits you, after one has been appointed.
To further complicate the matter, you've had this person appear on your behalf in a civil housing matter. Not only would you need the permission of the Court that assigned the Guardian, you would need the permission of the Housing Court.
If the Guardian is an ATTORNEY, and the attorney has APPEARED in the Housing Case, then what you are talking about is having a change of attorney, not removal of the guardian. This would be pretty complicated, though, and it is a conversation you would need to have WITH the Attorney who is acting as your Guardian.
This does not constitute legal advice or the engagement of my services as an attorney.
If the judge has appointed a guardian ad litem for you it is because that judge believes you need assistance in defending yourself in the proceeding. Once that guardian ad litem has been appointed it is unlikely that the judge will relieve her because you disagree with the way she is handling the case.
The above constitutes general information only and should not be considered legal advice.
