Can someone advise please

I have no idea, but I would imagine it would have an impact on you seeing your child/children if you stop paying? 

@fer17 complete different circumstances, I never mentioned I would not pay child maintenance (private agreement) .

I was wondering if its possible for the child maintenance to trace you if you change your name, and change it on all legal documents if you don't enroll it (for the government to see).

Also if you already have a case open with CMS, and change your name to stop a ex from tracing you and harassing's  you, will they know you changed your name automatically?

I am worried if they pass these details over to her.

Hi

They access your tax (HMRC) and DWP records via NI number which 0retty much covers large organisational tentacles.. If you legally change your name then you will have to (if you are on the radar) update details with these orgs and the CMS is part of DWP will real time access to HMRC so they will find out that way..

Also you bank details will show with your partner when transferring payment by BACS (if you do it this way) and so if you change name with bank then she will know.. 

@Daddyup Hi Mate, can always count on you for good advice thank you.

@Daddyup, is it legal to keep my bank account open in my first name? so that i can keep paying her money through my old name?

rather then give her my details of my new name?

I'm not sure what the motive is here.  If your ex is harassing you then you can apply for a non molestation order to stop it.  If the harassment is about child maintenance as long as you are paying the correct amount, she should not be harassing you.  You can keep your bank account open in your old name and pay her money though that.  If you stop paying, then she will likely find a reason to stop you seeing the child/ren.  The two things are completely separate and you will have to apply on a C100 to see the child/ren which could be long winded.   I would expect that CMS will be able to trace you through your NI number if you change your name and stop paying.

Hi

Legally based on the deed poll declaration you are to give up your old name which means you should change your name on your bank account. However you can just keep the account if its for sole purpose of this as I don't think there are any legal ramifications...

However, if you do go down this route and use old name on too many things or use that bank account for too many things then one impact you may have is on your credit rating as bank accounts in both names will show (your credit report will show a name change/alias anyway) and thus you may get caught up in financial institutions fraud markers when applying for new credit as your credit report will look a little all over the place if that makes sense? 

Otherwise not too many issues, but as Champagne says, not sure on the reasons for going down this route and there may be other options that are better.. 

@Daddyup it will be strictly for the purpose of just paying her, The bank account will not be used for anything else, 

Reason I am debating weather to change my name or not is genuinely because I really don't want her to trace me or cause me grief, she is a nightmare to deal with and so unpredictable. she's already causing a massive rift in my family life! but she's clever and nothing police can do.

My motive is looking for a solution for a peaceful life which is drama free, I just want a fresh start etc. as crazy as it sounds.

So if you keep open two separate bank accounts this is classed as fraud? and it will affect my credit score?

Everyone else so far thanks for the help!

what about if I just change my first name, but have the first name same letter?  for example (fake name) Daniel and change it to Dean?

When making bank payments for maintenance they will only see  MR D Surname

Hi

Not sure I follow, when you say you will change your name do you mean you will do deed poll and then just change the 1st name on the bank account that you use for CMS or everywhere?

Honestly I don't believe the name change solution will achieve what you want.

Different banks have different processes, some banks show full name when payment is made. However, the CMS will have to have your new name and anyway if you change it with HMRC or your employer who will pass it to HMRC then DWP/CMS will get it anyway.. Going down the deed poll route is a legal declaration etc.

Have bank accounts in 2 diff names is not automatically considered fraud (think of people who continue to hold accounts in maiden names for example) but it may flag up when you attempt new credit and you may not pass auto credit checking and instead you may be asked to explain and I don't believe the reason you provide will be accepted etc. 

As champagne said, if you are being harassed then keep a detailed diary and repot to the police and apply for a non molestation order. If you are paying CMS, are you seeing your kids?
