Hi Kerry
Your post does not make sense.
In your first paragraph you state that you asked for a MR for your PIP award as you was informed in 2022 that you have a terminal disease.
In your second paragraph you state 'the last contact with DLA was July 2019'
To apply for a out of time MR, the absolute time limit is 13 months from the decision date. You have not stated the date when your PIP was awarded.
