hi ashley,

I had applied for an affidavit of support for my daughter before at the Philippine Embassy in London and i have to apply again coz it expires after 6 months.

You can probably visit the website of the Philippine Embassy in London and under the category of Consular Services - Legalization, you can download the form 'affidavit of support', you can either use that and have it notarized from there or you can use that form as a guide when you write your own letter of support for your daughter.

Hope this may help, goodluck and all the best.
