Deed Poll as Symbolic Act

The "Deed Poll as Symbolic Act" names a structural operation within Lacanian semiotics wherein the legal act of changing one's name — the deed poll — is read not as a merely biographical or juridical event but as a signifying intervention within the paternal field. In Aubert's reading of Joyce (as presented in Seminar 23), the father's name change enacts a self-undermining movement: the Name-of-the-Father, which in classical Lacanian theory functions as the anchoring, stabilizing master-signifier (the point de capiton that arrests the sliding of the signifying chain), is here shown to be capable of poisoning itself — the father actively unsettles the very symbolic guarantee he is supposed to embody. The deed poll is thus a metonymy for the paternal signifier's fragility: by legally excising and replacing the name, the father performs a cut in the Symbolic that opens onto the Imaginary, triggering a slide from paternal symbolic authority toward the maternal imaginary register. The word "poll" — meaning a document that has been cut back or shorn — enacts formally what the act performs structurally: a truncation of the signifier's anchoring function.

This concept illuminates the precise mechanism by which the paternal function can fail from within rather than through simple absence (foreclosure). The deed poll does not foreclose the Name-of-the-Father in the clinical-psychotic sense; instead, it introduces a destabilizing internal torsion. The signifier 'Mud' — the residue of this nominal mutation — serves as the pivot through which the mother's hallucinatory return becomes possible, suggesting that when the paternal signifier cancels itself, jouissance previously bound under the Law of the Father re-emerges in the Real as spectral maternal presence. The deed poll is, in short, a symbolic act that inadvertently dismantles its own symbolic efficacy.

This concept appears in jacques-lacan-seminar-23-cormac-gallagher (p. 78), within Lacan's late Borromean period where attention shifts from clinical structure toward the question of how the sinthome can substitute for or compensate a failing Symbolic order — with Joyce as the privileged exemplar. The deed poll as symbolic act sits at the intersection of several cross-referenced canonical concepts. Most directly, it is a specification — indeed a pathological variant — of the Name-of-the-Father: where that concept normally designates the signifier that arrests metonymic sliding and institutes phallic signification, the deed poll demonstrates the Name-of-the-Father functioning as a "poisoned" signifier, one that turns against its own anchoring (point de capiton) function. Rather than securing the signifying chain, it releases it. This relates simultaneously to the paternal function, which here fails not through foreclosure (Verwerfung) but through a self-inflicted nominal mutilation — a subtler structural compromise that allows psychotic-adjacent effects (spectral returns, hallucination) without full psychotic structure.

The slide toward the maternal Imaginary that the deed poll initiates connects to the Imaginary register's property of consistency without symbolic regulation: once the paternal signifier is cut, the mother's image gains imaginary consistency and returns hallucinatorily. The signifier 'Mud' that emerges as pivot also resonates with the logic of jouissance: released from symbolic binding, jouissance returns in the Real as the mother's intrusive presence. The deed poll thus functions as a micro-demonstration of how the signifier can simultaneously produce and undermine the subject's symbolic scaffolding, making it an essential case study in Lacan's late engagement with Joyce and the sinthome as a fourth ring that compensates for a structurally compromised paternal knot.

according to a legal formula, which is called deed poll. Deed, namely an act, an act but poll evokes, describes in a way what the act is, from the point of view of the document. It is a document that is cut back.

The quote is theoretically loaded because it performs a semiotic decomposition of the term "deed poll" that mirrors the structural logic it is meant to illustrate: "deed" (act) and "poll" (cut back) together describe a signifying act that is constitutively truncated — an act whose very documentary form is one of excision. The word "cut back" (poll) resonates with the Lacanian notion of the signifier as always already marked by a cut, and foreshadows the argument that this particular act cuts not just paper but the symbolic authority of the paternal name itself.
