This is what what the rescript of dispensation actually looks like, although it is delivered in Latin and has to be given personally by the Bishop. The following is a translation of the Latin text in memory of Msg. Basil Kershaw:

Congregation for the Sacraments
Fr. X, priest of the diocese of X has requested a dispensation from priestly celibacy.

Our Most Holy Father John Paul II by Divine Providence Pope, on the {date}

having received a report of the case from the Sacred Congregation for the Doctrine of the Faith, grants the request according to the following conditions:

The rescript takes effect from the time or notification made to the petitioner by the competent ecclesiastical Authority, and covers inseparably dispensation from priestly celibacy and at the same time loss of clerical state. It is never lawful for the petitioner to separate those two elements, or to accept the one and refuse the other. If the petitioner is a religious, the rescript covers also dispensation from vows; likewise in addition it carries with it absolution from censures, in so far as needed.
Notice of the granting of dispensation is to be entered in the Baptism Register of the petitioner's parish.

As far as concerns the celebration of canonical marriage, the norms which are decreed in the Code of Canon Law are to be applied. But the Ordinary should take care that the affair should be carried out cautiously without show or external parade.

The ecclesiastical Authority, to whom it pertains to share the rescript with the petitioner, should earnestly exhort him to share in the new life of the People of God, by way of adapting to his new style of living, to maintain the structure and so show himself a great lover of the Church. But at the same time, let them make known to him the following:

a priest who has been dispensed by this process itself loses the rights proper to the clerical state, and the honours and ecclesiastical offices; he is no longer bound by other duties connected with the clerical state
he remains excluded from the exercise of the sacred ministry, with the exemption of those matters in Canons 976, 986§2, and therefore cannot give a homily. Moreover he cannot perform the extraordinary ministry of distributing holy communion nor can he undertake a leading office in the pastoral sphere.

Likewise he cannot fulfil any duty in Seminaries and in comparative Institutions. In other institutions of a higher grade of studies, which in any way depend on ecclesiastical Authority, he cannot perform an administrative position or the office of teaching.

In these same institutions of a higher grade of studies which do not depend on ecclesiastical Authority he can teach no discipline that is properly theological or connected closely with it.

Moreover in institutions of a lower grade of studies depending on ecclesiastical Authority he cannot perform an administrative post of the office of teaching, unless the Ordinary in accordance with his prudent judgement and without scandal, with regard to what pertains to the duty of teaching, has thought it right to decide otherwise. A dispensed priest is bound by the same law in teaching Religion in Institutions of the same kind which do not depend on ecclesiastical Authority.

Essentially a priest dispensed from priestly celibacy, and more so a priest who has married, ought to keep away from places where his previous state is known. However the Ordinary of the petitioner's place of residence, after consulting as far as necessary the Ordinary of incardination or Major Religious Superior will be able to dispense from this section concerning the Rescript, if the presence of the petitioner is not foreseen as likely to cause scandal.

Finally let some work of devotion or charity be imposed on him. At a suitable time a brief report should be made to the Sacred Congregation about the carrying out of the Rescript, and if any surprise of the faithful should arise in the end, it should be taken care of by a prudent explanation.

Anything to the contrary notwithstanding. From the Offices of the Sacred Congregation for the Doctrine of the Faith.
