The discovery of Edward Casaubon’s codicil changes the meaning of Dorothea’s marriage and the choices left to her after his death. When Celia explains that Casaubon’s will would strip Dorothea of his property if she married Will Ladislaw, the revelation exposes a concealed attempt to govern her future, brings her own feelings for Will newly into view, and turns inheritance into a conflict between justice, loyalty, and freedom from her dead husband’s power.

The condition and its disclosure

Celia is the one who tells Dorothea what Casaubon has done. She says he added a codicil directing that the property pass away from Dorothea if she married Will. Dorothea first responds that the property is of no consequence to her. Celia clarifies that the restriction is specific to a marriage with Will, rather than remarriage in general, and says that Sir James Chettam regards Casaubon’s action as abominable and ungentlemanly. Celia also offers Sir James’s interpretation: Casaubon meant to prevent Will from seeking Dorothea for her money. Her matter-of-fact delivery, amid the ordinary business of caring for her baby, contrasts with the upheaval the news produces in Dorothea.

The disclosure lands against the history of Casaubon’s expectations of marriage. He had chosen a much younger wife whom he imagined would be an appreciative and submissive helpmate, assist with his scholarly work, and sustain domestic life. He believed Dorothea could help him manage his research and had not considered with comparable care whether he could make her happy. The codicil extends that unequal expectation beyond his death: rather than leave Dorothea free to dispose of her inheritance, it makes her marriage to Will the condition for losing it.

A changed understanding of the past

Dorothea’s immediate reaction is not simple grief or relief. The news makes her reconsider Casaubon’s conduct, her dutiful feelings toward him, and the conflicts they had endured. She becomes conscious of a possible hidden suspicion in his thoughts, and feels a sudden repulsion from the husband she had tried to serve. Her experience is described as a metamorphosis: memory cannot readily adjust to a life whose meaning has changed. The codicil therefore reveals more than a term in a will. It alters Dorothea’s understanding of the marriage and of the motives that may have lain behind it.

At the same time, the restriction makes Will newly imaginable to her as a possible lover. Until this moment, Dorothea had not considered that she might marry him. Learning that Casaubon had treated such a union as a danger—and that Will might himself have perceived the possibility—awakens a sudden longing. That feeling arrives alongside the practical and moral obstacles, not after they have been resolved. Dorothea can identify that her world has changed, but not yet what she should do within it.

The estate, the research, and the remaining duties

At Lowick, Dorothea searches Casaubon’s desks and drawers for private writing addressed to her. She finds none. The papers instead include the beginning of his proposed directions for her work on his scholarly project, the Key to All Mythologies. Casaubon had hoped she would carry his research forward, though his own hesitation had left the plan incomplete. Dorothea had once been capable of accepting such labor as an act of faithfulness, even while doubting its usefulness. After the discovery, however, the promise is entangled with a newly perceived history of secrecy and suspicion; Casaubon’s intended hold on her through his work and his will has lost its former moral force.

The inheritance remains a question of duty as well as personal freedom. Dorothea would gladly be rid of the property and return to the fortune settled on her before her marriage, except that she believes ownership carries obligations she should not evade. She also thinks that half of Casaubon’s property ought, in justice, to go to Will. Yet the codicil makes that course difficult: an act that appeared to elude Casaubon’s purpose now feels to Dorothea like a triumphant defiance of him, and that prospect repels her even as she resents the means he used to prevent it. When she locks the empty desks and drawers again, there is no personal explanation or apology to help her settle the conflict.

Significance

The codicil makes the estate an instrument of control rather than a neutral inheritance. Casaubon’s restriction binds Dorothea’s economic future to a specific choice of husband, while also influencing whether she can act on her belief that Will has a moral claim to part of the property. The revelation exposes the limits of Dorothea’s earlier understanding of her marriage: her loyalty had rested on an image of Casaubon that his last provision unsettles.

The episode also gives Dorothea new knowledge of her own attachment. Will’s possibility as a husband is no longer merely an abstract implication of Casaubon’s suspicion; it becomes a feeling Dorothea must reckon with. But the moment supplies no easy resolution. Her affection, her concern for Will, her obligations as an owner, and her resistance to seeming to defeat Casaubon’s will pull in different directions. The codicil thus turns a private testamentary condition into a lasting moral and emotional problem.
