Delaying consummation of the marriage after doing the marriage contract
Question

                A young man came and proposed marriage to me, but I was surprised to see his family objecting strongly to that, and they caused a great deal of trouble for him. I suggested to him that we do the marriage contract on paper for now, and we will stay apart from one another for some of the time, especially since I want to leave my current job and I have many entitlements that I cannot take unless I am married. Is there anything Islamically wrong with doing the marriage contract in this manner and delaying the consummation of the marriage?.
Praise be to Allah.Firstly: 
We ask 
    Allaah to help you and guide you, and to compensate you with something 
    better if you leave your job, and to bless you with a righteous husband who 
    will be a delight to you.  
Secondly: 
If the 
    marriage contract is done with the consent of both parties and in the 
    presence of the woman’s wali (guardian) and two witnesses, then it is a 
    valid marriage, whether the consummation takes place immediately afterwards 
    or it is delayed for a long time or a short time. 
The 
    Messenger  (peace and blessings of Allaah be upon him) did the marriage 
    contract with ‘Aa’ishah when he was in Makkah, and he consummated the 
    marriage with her three years later. Narrated by al-Bukhaari (3894) and 
    Muslim (1422). 
Thirdly: 
It is better 
    for him to try and convince his parents of this marriage, because that will 
    be beneficial for him and for you and your children. He should try not to do 
    this marriage without the agreement of his family, so that it will not be a 
    cause of never-ending disputes and arguments or have a bad effect on your 
    family life. 
Fourthly: 
It should be 
    noted that it is not permissible for you to form a relationship with this 
    young man, and that the fiancé is a stranger (non-mahram) to his fiancée 
    until the marriage contract is done.
And Allaah 
    knows best.
