It is because usercustom is not declared when you tried to send POST request. You need to rename custom_form variable to usercustom. I have simplified your code for you.

def signup(request):
    registered = False
    if request.method == "POST":
        user_form = UserForm(request.POST or None)
        usercustom = UserCustom(request.POST or None)

        if user_form.is_valid() and usercustom.is_valid():
            user = user_form.save(commit=False)
            user.save()

            custom = usercustom.save(commit=False)
            custom.user = user
            custom.save()

            registered = True
        else:
            print(user_form.errors, usercustom.errors)

    else:
        user_form = UserForm()
        usercustom = UserCustom()

    return render(request,'form.html',{'user_form':user_form,'usercustom':usercustom,'registered':registered})
