Are you seeing more personality disorders in litigation – yes, I can tell you that I am . . .

The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) classifies 10 primary personality disorders into three Clusters based on shared symptoms – and yes, I am seeing more of these disorders in personalities and relationships in litigation.

I have done litigation, trials, and mediation for a long time, but whether it is simply timing or a long-term trend, since 2019 I have had and seen more cases and situations where an opposing party wasn’t simply presenting aggressive legal advocacy for their position but exhibited a pervasive lack of empathy, need to be control, need to win or to be the winner, or need to be seen as the person who is right and the winner, lying (gaslighting, fraud and deceit – including by omission, obfuscation, hiding, or selectively using, spinning or twisting or misrepresenting facts, the situation, information, documents and evidence), bullying, undue influence, excessive or wrongful persuasion, unreasonable delay tactics, the gambler, theft and stealing, the thief, working for or concocting “gotcha” moments, or a pervasive lack of ability to reasonably evaluate or acknowledge the weaknesses in their side and that the other sides also have strengths. And correspondingly, they cannot allow the other person to have success, or to be right, or to win, or to prove them wrong, or to appear so.

I have also provided below a copy of my undue influence eBook, a link to a discussion about abuse of process, and my personality and relationship scale.

The personality disorders that I see most often in litigation are Cluster B disorders, but they tend to be strong Cluster B disorders – in other words, we are not simply talking about aggressive legal advocacy. Unfortunately, through their strategies and tactics such a party’s position can seem correct or plausible to an outside viewer. It often takes considerable time and effort to disprove their position – it is easy to make several short or one- or two-sentence untrue arguments or positions or allegations – it takes considerably greater effort to then disprove the untruths. Of course, the intent of the wrongdoing party is to prevail, even through what might be an unlawful abuse of process – I have found that the only way to defeat the wrongdoing party is to effectively present the truth, fight against the wrongdoing party and not give in, and show as many as possible of the wrongdoing party’s untruths, falsities and fallacies. You might in the end sufficiently convince the wrongdoing party that she or he has significant weakness and might lose, but you cannot count on that happening and you do need to prepare for trial and have the resolve that the disputes will go to trial.  

The following is a summary of the DSM-5 Clusters and personality (and relationship) disorders.

Cluster A personality disorders (odd or eccentric) –

Paranoid – Pervasive distrust and suspicion of others.

Schizoid – Detachment from social relationships and a restricted range of emotional expression.

Schizotypal – Acute discomfort with close relationships, and cognitive or perceptual distortions and eccentricities.

Cluster B personality disorders (dramatic, emotional, erratic, disregard, or lack of empathy) –

Antisocial – A pervasive pattern of disregard for and violation of the rights of others. 

Borderline – Instability in interpersonal relationships, self-image, and affects, and marked impulsivity. 

Histrionic – Excessive emotionality and attention-seeking.

Narcissistic – Grandiosity, a need for admiration, and a lack of empathy.

Cluster C personality disorders (anxious or fearful) –

Avoidant – A pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation.

Dependent – A pervasive and excessive need to be taken care of that leads to submissive and clinging behavior and fears of separation.

Obsessive-compulsive – A pervasive preoccupation with orderliness, perfectionism, and control.

The following is my personality and relationship scale. As the scale moves to the right the personality or relationship becomes more troubling, dysfunctional and damaging to other people – you need to protect yourself, be prudent out there, and avoid or get out of or stay away from some personalities and relationships:

Goebner v. Superior Court – in Probate Court the timing for bringing a demurrer is determined under Probate Code provisions not under the Code of Civil Procedure

The following is a brief discussion about the recent holding in Goebner v. Superior Court (2025) 110 Cal. App. 5th 1105.

In relevant part, the Court in Goebner held that the timing for the filing of a demurrer in a probate court case is governed by the California Probate Code provisions for the bringing of a response or objection to the petition and is not governed by the California Code of Civil Procedure.

The holding is important not only to the particular case in question but also for attorneys who practice in the Probate Court. This has been an issue that I have run into in my cases many times. For example, in response to a petition a demurrer might be filed in which the respondent argues that the petition is in some manner defective or fails to state a claim. Some Judges in Probate Court are receptive to the filing of a demurrer, some Judges in Probate Court are not receptive to the filing of a demurrer, and as addressed in Goebner, in the Probate Court there can be questions whether Probate Code rules or rules of civil procedure apply.

In Goebner a demurrer was filed just two days before the hearing. Under the Probate Code a response or objection to a petition can be filed in writing at the time of the initial hearing and also can be made orally at the initial hearing. But under the rules of Civil Procedure a response or objection to the complaint is due 30 days after service of the complaint on the party.

In Goebner the Probate trial court held that the demurrer was filed too late. The Court of Appeal overruled, holding that under the Probate Code a responsive objection such as a demurrer can be brought as late as at the initial hearing. Note however, although permissible, if at all possible, I do not recommend waiting until the day of the hearing to file or bring a demurrer to the petition – instead, it is better to file a written demurrer upon available time prior to the initial hearing.

Although not the primary issue, the holding in Goebner also is relevant as it confirms that demurrer can be brought in response to and against a petition that is brought in the Probate Court, and that responses and objections in Probate Court can be made according the Probate Court procedures just prior to and even at the initial hearing (although, again, in my view, if possible it is better practice to try to not wait so long).

As the pleadings (i.e., the petition in a Probate Court case, or the complaint in a civil action) set the scope and boundaries of the relevant claims and issues to be resolved in the case, I do find it useful in appropriate circumstances to file a demurrer to try to ensure that the claims made are sufficient pleaded and are not vague or ambiguous.

The following quotes are some of the relevant discussions from the holding in Goebner:

  • Section 1000 provides, in relevant part, “Except to the extent that [the Probate Code] provides applicable rules, the rules of practice applicable to civil actions … apply to, and constitute the rules of practice” in proceedings under the Probate Code. (§ 1000, subd. (a).) This is a rule of default — that is, the Probate Code “adopts the civil practice rules only where special rules are not prescribed.”
  • Under the plain language of the Probate Code, it “does provide specially applicable rules” that address the timing for filing a response or objection to a petition. (citations omitted)
  • Within that chapter is section 1043, providing “[a]n interested person may appear and make a response or objection in writing at or before the hearing.” (§ 1043, subd. (a), italics added.) Similarly, interested persons “may appear and make a response or objection orally at the hearing.” (Id., subd. (b), italics added.) The statute underscores that oral objections may be made initially at the hearing by noting that the “court in its discretion” may “grant a continuance for the purpose of allowing a response or objection to be made in writing.” (Ibid.)
  • While the Probate Code does not expressly define “objection[s]” to include demurrers, we conclude that interpretation is appropriate. Pursuant to section 1000 we look to the Code of Civil Procedure (§ 1000, subd. (a).) The Code of Civil Procedure recognizes that a demurrer is a form of an objection to a petition or complaint. (Code Civ. Proc., §430.30, subd. (a) [a “ground for objection to a complaint, cross-complaint or answer” “may be taken by a demurrer to the pleading”]; see also id. §430.10 [party “may object, by demurrer” on enumerated grounds] . . .. (citations omitted)
  • Indeed, Code of Civil Procedure part 2, title 6, chapter 3, article 1, which includes these provisions, is titled “Objections to Pleadings.” Reading these Probate Code and Code of Civil Procedure statutes together, an interested party may file a demurrer to a petition under the Probate Code “at or before the hearing.” (citations omitted) The Probate Code further addresses concerns that a party may present a demurrer at a hearing — thus placing the petitioner at a disadvantage — by allowing a court to “continue or postpone any hearing, from time to time, in the interest of justice.”1 (§ 1045.) The deadline in the Code of Civil Procedure to respond and object within 30 days after a complaint is served is inapposite.

Gaslighting and other bad persons and personalities – forwarding from The Atlantic – bad people and personalities are more common

The following is a link from Yahoo to a discussion from an author in The Atlantic about gaslighting and other personalities, and defenses. https://www.yahoo.com/news/spot-stop-sociopath-160000775.html?guccounter=1

I believe that these bad people and personalities are more common in people than reported or thought. Note: I do not know the author of the article or his expertise – I am posting the link for discussion purposes only. Particularly since 2019 (i.e., even prior to COVID) the numbers of situations and people and cases that I have directly or indirectly been involved in that have involved varying levels or degrees of opposing bad people with dysfunctional personalities have increased to a shocking level (including cases and situations involving fraud, deceit, concealment, control, possession, false narrative, lying, undue influence and excessive persuasion, and use of the law and the court’s for wrongful purposes and wrongful intentions to see what they can get away with (e.g., lawfare, litigationfare, courtfare)) . This is unfortunate of course, and also because there truly are good, sharing, helpful, honest and truthful people. But everyone needs to protect themselves. As the author discusses, there are many different “bad” persons and personality types.
