even his relatives blocked even i ask them to force their son to support us

Only you can decide if it is practical but you start with your local Court and then seek to have it enforced, now for that to happen in the UK you need to know where he is and of course that he has money they can go after.

Could it be possible that the children should receive UK child benifit.

Well sort of, the UK authorities would seek to enforce any award.

Child benefit is a universal benifit paid by the government directly to the mother. I don't know how much it would be but was about £25 per child per week so not insignificant in the Philippines. Child support is something totally different and paid to the mother by the absent parent.

UK child benefit can only be paid to uk resident beneficiaries

Not worth doing anything if your husband hasn't got a decent income now. Did he maintain his job through the pandemic?

It can actually be paid to people living abroad too, but only in certain countries. Sadly for the OP, the Philippines isn’t among them. https://www.gov.uk/child-benefit-abroad

Yes but if the husband is not a total ahole he could set it up in the uk for her to draw.

I think that is when you are getting it and move.

Nether her or the children are UK resident.

I don't know if it is still the case but it was not unusual for eu workers to claim for their children back in easter Europe.

Exempted as they were workers. They needed to show they planned to stay. Also included Swiss and those from the EEA.

British law will apply to the husband if he is living in the UK, if he is on benefits some of that money will be taken off the benefits - it is not a huge amount but it would go quite far in the PI. If he has a decent income then it becomes serious dosh for PI. There are some lawyers in the PI who will pursue the matter for free in return for a cut of the proceeds. Would probably have to have his name on the birth certificate.

We don't know the background, though, if a Filipino boyfriend is lurking in the background then it would be important that he can't get a cut of the money.

BTW EU women in the UK could claim child benefit even if their kids were back home so it is probably necessary for the Filipina to be in the UK to do that.

I'm not sure if this would apply to your circumstances?
