you should contact yourlocal housing office tomorrow in person. they will look for a place at a womens refuge. a taxi will get you there. so you should be able to manage your children and at least a suitcase.
if you really want to get out - your material posessions shouldnt be your concern.
you should start thinking about what you are likley to need tomorrow for your children. do you need to do some washing this evening - doing some washing will not look out of place
if your partner works, the kids could go to school as normal.
then you can pack a suitcase, carrier bags etc.
you need to get together any documentation you are likley to need for your future
things like
birth certificates for you and your children
your appointment card /notes for your pregnancy and antinatal care, passports, provisional driving liscence,
you should think on how you can get some money - can you get to the bank? will you need your bank cards, credit cards.
will you need to phone your debtors and tell them to suspend your accounts ( catalogues etc) so HE cannot run up debt in your absence.
think about your housing. If you own your house - you are going to need advice from a solicitor
if your name is on the house as a tenant - He will be forcably removed and unliley to be re-housed as the perpetrator.
if the house is in his name as a tenant - the council or social landlord and evict him for this behaviour.
if its joint tenancies - it may be more difficult - you will have to seek advice from your landlord.
it is not possible to have two social housing tenancies - so if you have your name on one - getting re-housed is going to be difficult until either he is removed from the premesis or your name is removed from the tenancy.
if you private rent - i dunno!
so
clothes
document
and carrier bags with tinned goods and food etc - becuase the refuge dont feed you!
benefit details NI number
Child benefit Number
thing of all the things you are going to need -t hat you will not be able to come back for later.
you can descretely do some of this this evening. washing , gathering of documents and phone numbers you will need etc.
then tomorrow you can go to the housing ask about a place at a refuge, pack, get together the rest of what you need. arrange for taxi, phone school ask them to have children ready for collection becuase you have family emergency.
good luck!
