Does changing my name invalidate my will?

[CruCru]

I have just changed my name using one of those online deed polls (basically just adding my maiden name as my middle name). However, my Will names me only as Firstname Surname. Does this matter?

No, it will be fine. You might want to keep the deed poll document with the will and it can be a good idea to update wills regularly so now may be a good time.

yes it can, change your will with your former name and your new name.
