The word Domicile has a very extensive etymology, it comes from the Latin “Domus Collere” which means house that is inhabited and Spouse, which derives from the Latin of a compound word, “Coniux or Coniugis” used to designate either of the two belonging persons to a marriage, along with "Iugum" which is where "Yugo" comes from, then spouse was initially translated as "united by a yoke". The Domicile can be said to be the place of residence of an individual, it is a specific place with its own and unique address, in that place people can be located.
It is common for this address to be a requirement demanded by many procedures in any country. Then, since there is a marriage document, the signatories as husband and wife establish a joint place of residence and domicile that translates as that place where they carry out all the activities of that stable de facto or legal union. Both parties must agree to establish the space to live together, and in the same way, if they decide to move from that address, it must be approved by both.
The marital home is that physical space where the spouses and children (when they exist) reside, therefore it is also called a family home or home. However, it must be taken into account that in order to say that there is a marital home, the spouses must have full authority over the home, that is, it cannot be a space shared with another family (either the parent of the spouses, family of the same or a third party), however this does not mean that it must belong to them, it can be a rented house.
Formerly it could be imposed by the husband (man) because he was considered the father of the family and was the one who had the authority to decide the different areas corresponding to marriage and the wife obeyed it, now with the reinvention of women's rights, it is between The two define the character of a marital home. If there is a divorce in the marriage, the marital domicile will cease to exist and it will be a lawyer or a judge who indicates what will happen with the house, since all divorce cases are not equal.
