- Get the deposit protected asap - use the custodial scheme, as you don't have to answer many questions. AFAIK no tenant has succeeded in getting compensation when the deposit has been protected before hearing.
- Don't bother with the s21 route unless absolutely necessary - invariably it will take longer than s8 when defended.
- For repossessing your property, use s8, grounds 8, 10, and 11. The advantage with this is that you also get a money order (if you ask for it as part of your claim). Also, it is more vindictive (rightly so!) as an additional advantage is that most councils regard rent arrears as being 'intentionally homeless' so they won't be using you to get into social housing ahead of the queue.
On some things I am very knowledgeable, on other things I am stupid. Trouble is, sometimes I discover that the former is the latter or vice versa, and I don't know this until later - maybe even much later. Because of the number of posts I have done, I am now a Senior Member. However, read anything I write with the above in mind.
