OK, here's my translation. I think I should be safe to copy and paste it as I have followed Cinefactus's advice to use round brackets. It goes against the grain though!
Damages £6 whereof 20s to the clerks. Half(?) ... mark(?)
By virtue of which record, at the suit of the aforesaid Alice, asserting that execution of the aforesaid judgment had not yet been done, order was sent to the Sheriff that, through two etc (trustworthy men? – compare Beatrix and del Clay below), he should cause the aforesaid William de Spanneby to know that he should be before the King in the octave of Saint Michael next in the past, wherever (the court might be) etc, to show whether etc, or if he can say (literally knows (how) to say) why the aforesaid Alice ought not to have her seisin of the aforesaid tenements, together with damages etc.
And further etc, that the court etc.
On which day the Sheriff returns that the aforesaid William is dead, for which (reason) order was sent to the Sheriff that, through two etc, he should cause Master John de Spanneby, and Hugh de Spanneby, and John the son of the same Hugh, tenants of the aforesaid lands and tenements, as it is said, to know that they should be before the King in the octave of Saint Martin next following, wherever etc, to show whether etc, or if they can say why the aforesaid Alice ought not to have her seisin of the aforesaid tenements, together with damages etc, according to the aforesaid recovery (ie a common recovery, means of transferring land).
And further etc, that the court etc.
On which day the aforesaid Alice comes, through Simon Underwode her attorney,
And the Sheriff returns that he has caused the aforesaid Master John, Hugh and John, to know, (ie served them with a writ of scire facias), through William Beatrix of Wylughby and Gilbert del Clay of the same, who come according to the aforesaid forewarning,
And the aforesaid Alice seeks execution etc.
And the aforesaid Master John says that he holds the aforesaid tenements, with the appurtenances, for the term of his life, by fine levied in the court of our Lord the King,
Which tenements, indeed, after the death of this Master John, will remain to the aforenamed Hugh de Spanneby for the term of his life,
After whose death the aforesaid tenements, with the appurtenances, will remain to the aforesaid John the son of Hugh and the heirs begotten of his body.
And he says that the aforesaid Alice, after the aforesaid judgment etc, by her writing, which the aforesaid Master John proffers here in court, remised, released and utterly quitclaimed the aforesaid tenements, with the appurtenances, to the aforesaid William, while he lived. The tenor of the writing is such:
To all those, to the notice of whom (these) presents shall have come, Alice de Neyvill (sends) greeting.
May you know me to have released, remised and utterly quitclaimed, from me and my heirs to Sir (courtesy title for a priest) William de Spanneby, clerk, all those tenements, with all their appurtenances and reversions whatsoever, which I recovered against him at Boston, before the Justices of our Lord the King assigned to hold assizes in the county of Lincoln,
So that neither I, nor anyone in my name or (that) of my heirs, shall be able in the future to demand any right or claim in the aforesaid tenements.
These being witnesses, Sir John Goband (and) Sir John de Byortbor’, knights, John de Lyndeseye of Morton, William de Vruy of Wolcote(?), John the son of John (or Johnson) of Billingborough, Robert Lonet (or Lovet) of Newton, Geoffrey of the same, and others.
Given at Boston on the 6th day of August in the second year of the reign of King Edward the son of King Edward.
And he seeks judgment whether the aforesaid Alice ought to have execution of the aforesaid tenements contrary to her deed etc.
And the same Alice, having had sight of the aforesaid writing, says that it is not her deed, and upon this she puts herself upon both the country and the witnesses etc. (I think putting oneself super patriam means asking to be judged by a local jury.)
And the aforesaid Master John and others similarly.
Therefore order (is sent) to the Sheriff that he should cause both 24 etc (upright and trustworthy men of his shrievalty), and the aforesaid witnesses etc, to come before the king a month from Easter Day, wherever etc, to give recognizance(?) etc.
And so far as (concerns) execution of damages etc, they say that they were not forewarned as heirs or executors of the aforesaid William, but merely as tenants of the aforesaid tenements, (and) they seek judgment etc.
And the aforesaid Alice is not able to deny this.
Therefore it is said to the same Alice that she should prosecute against the heirs or executors of the aforesaid William concerning the aforesaid damages, if it should seem (fitting) to her to pursue (this) etc.
And hereupon the aforesaid Alice seeks a writ against the aforesaid Hugh de Spanneby, brother and heir of the aforesaid William, for damages etc.
Therefore order (is sent) to the Sheriff that, through two etc, he should cause the same Hugh to know that he should be before the King at the aforesaid term, to show whether etc, or if he can say why the aforesaid damages ought not to be made out of his lands and chattels etc.
And further etc, that the court etc.
Moreover, on the morrow of the Purification of the Blessed Mary in the fourteenth year of the reign of the now King, come the aforesaid Master John de Spanneby, Hugh de Spanneby and John the son of the same Hugh, in their own persons,
And similarly come the jurors of the county of Lincoln, and the witnesses named in the said writing,
And the aforesaid Alice, although solemnly and repeatedly called, does not come to prosecute that which she pretended above,
Therefore the said Alice is in mercy,
And the aforesaid Master John and the others (are dismissed) therefrom without a date (for returning),
And the aforesaid writing, which previously remained in the possession of the court, is returned to the aforenamed Master John de Spanneby etc in court etc.
