Short answer. Yes. The Rules presume that a writing is truly dated, so the date on the face of a document is taken as correct until someone shows otherwise. The presumption is disputable, and the party alleging that a document was backdated carries the burden of proving it.

The presumption in four words
Among the disputable presumptions in Section 3 of Rule 131 is one of the shortest in the list: that a writing is truly dated. Brevity is not weakness here. The presumption means that when a document is offered in evidence, the date appearing on it is taken as the date it bears out, without the party relying on it having to prove separately that the date is genuine. Given how many rights turn on sequence, this is one of the more frequently useful presumptions in ordinary civil litigation.
Why the date so often decides things
Dates carry more legal weight than their size on the page suggests. Whether a claim was brought in time, which of two conflicting documents came first, whether an act preceded or followed a transfer, whether a signatory had authority when he signed: each of these turns on when a writing was made. An allegation of backdating is therefore an attack on the document's operative fact rather than a quibble about a detail. The presumption ensures that such an attack has to be made and supported, not merely floated.
The burden of showing a false date
Because Section 3 presumptions are satisfactory if uncontradicted, but may be contradicted and overcome by other evidence, an allegation of backdating is the alleging party's to prove. Assertion is not contradiction. What tends to do the work is extrinsic material inconsistent with the stated date, such as records showing where a signatory was, correspondence referring to the document, or the circumstances of its production. Whether any of that suffices is for the court, but the presumption means the document stands in the meantime.
Related presumptions on the same list
The truly-dated presumption sits alongside others that push in the same direction. The Rules presume that private transactions have been fair and regular, that the ordinary course of business has been followed, and that a person takes ordinary care of his or her concerns. None of these decides a case. What they do is set the default: documents and dealings are approached as regular, and irregularity is something the party asserting it must establish. All of them are disputable and all yield to contrary evidence.
