urgent advice needed about maternity allowance and mixed (self-employed/paye) employment

[gobblygook]

One of my sister's is due in mid December. She has, stupidly, left it really late to apply for maternity allowance and is now in a pickle about what she should be applying for.

She has been on a fixed part time contract (a year) which ends as she goes on a maternity leave/just before baby due. She paid tax at source. She also has additional work and this is self employed and she pays her own tax/NI.

What allowance is she entitled to? What form does she fill out - and is she too late?

Thanks

She could try putting in her details here:

I'm self employed, so may be a little different, but the above web site from IssyStark will have the forms she can download. I sent mine off and 2 weeks have started to get paid so may not be too late. PS my accountant filled in all the bits and bobs i didnt know what to say!!
