Hello OP,
There is absolutely nothing illegal whatsoever with what you plan to do and it is a perfectly sound plan and I would say it is a very wise plan. Well done for saving £80,000 and enjoy the purchase of a property that will benefit you, your DD and whoever else lives with you.
Unfortunately, this is a classic example of why you should not share your personal financial information with jealous idiot friends or anyone really it’s got nothing to do with. Now, you’ve gone further and shared it with the whole world of Mumsnet, and unfortunately there’s even more idiots on here, most without premium bonds, or even any money.
If you would’ve just kept your business your business and cracked on doing whatever you planned to do with the house purchase, there will be no issues. As others have already said, you can withdraw your DD’s premium bonds up until her 16th birthday.
Some of the answers you have been given on here are laughable.
I also own premium bonds, I am an ex-mortgage advisor and also I have set up a premium bond account for my DD.
As the legal guardian of your DD, I assume you set up the premium bond account for your DD. If you were the one that set up the account and are the person responsible and have all the passwords and access you are free to withdraw the premium bonds from your DD’s premium bond account to whatever bank account you set up, which I assume is your bank account.
Yes, a mortgage company might ask for proof of deposit, in this case £50,000 of premium bonds in your name will work. Even showing the £30,000 in your daughters account will also be okay, however, if you have any doubts about this, simply withdraw the £30,000 now and get it safely into your bank account. if proof of funds are asked during your application, months and months down the line, you will have the £30,000 in your account in your name showing for several months.
As long as you are the person responsible for your daughters premium bonds, you can do anything you like with them. There is absolutely nothing Illegal about this, this is money that you have saved for your daughter and you have full custody of the funds until she is 16. You have not given your money away at all in this case.
I am sure that a very simple Google search, or a five minute look through the premium bonds terms and conditions will verify this for you and would’ve prevented a lot of doubt and speculation and ridiculous answers from stupid people.
Good luck with your house purchase and I recommend you do not share personal financial information with anyone except people who know what they are talking about and are impartial to your situation. Premium bonds would’ve let you know all you need to know with a simple email or phone call.
