A relative may give testimony with regard to his relative's signature.
What is implied? There was a legal document which Reuven and Shimon signed as witnesses. They died or traveled overseas. Reuven's son came and testified: "This is my father's signature," and Shimon's son came and testified: "This is my father's signature," it is as if they are two acceptable witnesses who are not related to the witnesses who have signed. If a third witness joins together with them and testifies with regard to the two signatures, the authenticity of the legal document is validated.
אמֵעִיד קָרוֹב עַל כְּתַב קְרוֹבוֹ. כֵּיצַד. שְׁטָר שֶׁעֵדָיו רְאוּבֵן וְשִׁמְעוֹן וּמֵתוּ אוֹ שֶׁהָלְכוּ לִמְדִינַת הַיָּם וּבָא בְּנוֹ שֶׁל רְאוּבֵן וְאָמַר זֶה כְּתַב יָדוֹ שֶׁל אָבִי וּבָא בְּנוֹ שֶׁל שִׁמְעוֹן וְאָמַר זֶה כְּתַב יָדוֹ שֶׁל אָבִי הֲרֵי אֵלּוּ כִּשְׁנֵי עֵדִים כְּשֵׁרִים שֶׁאֵינָן קְרוֹבִים וְאִם יִצְטָרֵף עִמָּהֶם שְׁלִישִׁי וְהֵעִיד עַל כְּתַב יָדָן שֶׁל שְׁנֵיהֶם הֲרֵי נִתְקַיֵּם הַשְּׁטָר:
The statements of the following individuals are acceptable when, as adults, they testify with regard to what they observed as minors. A person's words is accepted when, as an adult, he states: "This is the signature of my father....", "This is the signature of my teacher...", "This is the signature of my brother which I learned to recognize when I was a minor."
The above applies, provided he is joined by another person who learned to recognize these signatures while an adult.
בוְאֵלּוּ מִדְּבָרִים שֶׁנֶּאֱמָנִים הַגְּדוֹלִים לְהָעִיד בְּגָדְלָם מַה שֶּׁרָאוּ בְּקָטְנָם. נֶאֱמָן אָדָם לוֹמַר כְּשֶׁהוּא גָּדוֹל זֶהוּ כְּתַב יָדוֹ שֶׁל אָבִי זֶהוּ כְּתַב יָדוֹ שֶׁל רַבִּי זֶהוּ כְּתַב יָדוֹ שֶׁל אָחִי שֶׁהָיִיתִי מַכִּיר בִּכְתַב יָדָם כְּשֶׁהָיִיתִי קָטָן. וְהוּא שֶׁיִּצְטָרֵף עִמּוֹ אַחֵר שֶׁמַּכִּיר כְּתַב יָדָן כְּשֶׁהוּא גָּדוֹל:
When there is a legal document on which Reuven and Shimon signed as witnesses and two others came and testified to the authenticity of the signatures of both Reuven and Shimon, the legal document is validated. If, however, one testified to the authenticity of Reuven's signature and the other testified to the authenticity of Shimon's signature, the document is not validated. The rationale is that two witnesses must testify with regard to both witnesses' signature. If there is a third witness who testifies with regard to the authenticity of both Reuven's and Shimon's signature, the document is validated.
גשְׁטָר שֶׁעֵדָיו רְאוּבֵן וְשִׁמְעוֹן וּבָאוּ שְׁנַיִם וְהֵעִידוּ שֶׁזֶּה כְּתַב יָדוֹ שֶׁל רְאוּבֵן וְזֶה כְּתַב יָדוֹ שֶׁל שִׁמְעוֹן נִתְקַיֵּם הַשְּׁטָר. אֲבָל אִם הֵעִיד זֶה עַל כְּתַב יָדוֹ [שֶׁל] רְאוּבֵן וְהַשֵּׁנִי הֵעִיד עַל כְּתַב יָדוֹ [שֶׁל] שִׁמְעוֹן לֹא נִתְקַיֵּם הַשְּׁטָר לְפִי שֶׁצָּרִיךְ שְׁנֵי עֵדִים עַל כְּתַב [כָּל] יַד אֶחָד מִשְּׁנֵיהֶם. וְאִם יֵשׁ שְׁלִישִׁי מֵעִיד עַל כְּתַב רְאוּבֵן וְשִׁמְעוֹן כְּאֶחָד נִתְקַיֵּם:
When one witness says: "This is my signature," and he and another witness testify with regard to the signature of the other witness, the document is not validated, for three fourths of the money mentioned in the legal document is dependent on the testimony of one person. Similarly, if the son or the brother of the first witness testifies with another person with regard to the signature of the second witness, the document is not validated, because three fourths of the money is dependent on the testimony of relatives.
דאָמַר הָרִאשׁוֹן זֶה כְּתַב יָדִי וְהֵעִיד הוּא וְאַחֵר עַל כְּתַב יְדֵי הַשֵּׁנִי לֹא נִתְקַיֵּם לְפִי שֶׁנִּמְצָא שְׁלֹשֶׁת רִבְעֵי הַמָּמוֹן שֶׁבַּשְּׁטָר תָּלוּי בְּעֵדוּת הָאֶחָד. וְכֵן אִם הֵעִיד אָחִיו אוֹ בְּנוֹ שֶׁל רִאשׁוֹן עִם אַחֵר עַל כְּתַב יְדֵי הַשֵּׁנִי לֹא נִתְקַיֵּם שֶׁהֲרֵי שְׁלֹשֶׁת רִבְעֵי הַמָּמוֹן תָּלוּי בְּעֵדוּת הַקְּרוֹבִים:
When two witnesses sign a legal document and one of them dies, it is necessary that two witnesses testify with regard to the authenticity of the witness who died. If there is only one other witness who recognizes his signature in addition to the witness who is alive, the latter should write his signature, even on a shard, in the presence of two witnesses and send it to the court so that his signature will be validated. In that instance, it is not necessary for him to declare that it is his signature. Accordingly, he and another person can testify with regard to the signature of the deceased person so that his signature will be validated even though he is not present.

Mishneh Torah (Moznaim)
Featuring a modern English translation and a commentary that presents a digest of the centuries of Torah scholarship which have been devoted to the study of the Mishneh Torah by Maimonides.
The following principles apply if three judges sit together to validate the authenticity of a legal document, two of them recognize the signatures of the witnesses and one of them does not. Before the judges sign the validation, the two witnesses who recognize the signatures may deliver testimony before the third judge. Then they may sign the validation, for witnesses may serve as judges in a matter that is a Rabbinic ordinance, as we explained.
If the two witnesses who recognize the signatures sign the validation before testifying, they may not testify in the presence of the third judge and have him sign. For at the time they signed, only those two recognized the signature of the witnesses. A legal document may be validated only when all three judges recognize the signatures or witnesses deliver testimony on the signatures before each one of them.
ושְׁלֹשָׁה שֶׁיָּשְׁבוּ לְקַיֵּם אֶת הַשְּׁטָר שְׁנַיִם מֵהֶן מַכִּירִין חֲתִימַת יְדֵי עֵדִים וְאֶחָד אֵינוֹ מַכִּיר. עַד שֶׁלֹּא חָתְמוּ מְעִידִין בְּפָנָיו וְחוֹתֵם. שֶׁהָעֵדִים נַעֲשִׂים דַּיָּנִים בְּדָבָר שֶׁהוּא מִדִּבְרֵיהֶם כְּמוֹ שֶׁבֵּאַרְנוּ. אֲבָל אַחַר שֶׁחָתְמוּ אֵין מְעִידִין בְּפָנָיו וְחוֹתֵם [שֶׁהֲרֵי בְּעֵת שֶׁחָתְמוּ לֹא הָיוּ מַכִּירִין אֶלָּא הַשְּׁנַיִם] וְאֵין מְקַיְּמִין אֶלָּא עַד שֶׁיִּהְיוּ שְׁלָשְׁתָּן מַכִּירִין אוֹ יָעִידוּ הָעֵדִים עַל הַכְּתָב בִּפְנֵי כָּל אֶחָד וְאֶחָד:
The following law applies when the two witnesses who signed on a legal document died and two others came and testified, saying: "This is their signature, but they signed under duress," "...they were minors," or "...they were unacceptable as witnesses." Even though there were other witnesses who testify with regard to their signatures or their signatures could be recognized from another legal document concerning which a protest was raised and afterwards, it was validated by the court, the legal document is not validated. Instead, the two witnesses who signed the document are balanced against the two who testified that they were unacceptable as witnesses, and the legal document may not be used to expropriate money.
