(a)that in respect of the same marriage proceedings for divorce or nullity of marriage are continuing in a related jurisdiction; and
(b)that the parties to the marriage have resided together after its celebration; and
(c)that the place where they resided together when the proceedings in the court were begun or, if they did not then reside together, where they last resided together before those proceedings were begun, is in that jurisdiction; and
(d)that either of the said parties was habitually resident in that jurisdiction throughout the year ending with the date on which they last resided together before the date on which the proceedings in the court were begun,
